Urban archaeology is a sub discipline of archaeology specializing in the material past of towns and cities where long-term human habitation has often left a rich record of the past. In modern times, when someone talks about living in a city, they are in an area with many surrounding people and buildings, generally quite tall ones. In archaeological terms, cities give great information because of the infrastructure they have and amounts of people that were around one another. Through the years there has been one big method used for urban archaeology along with significant historic developments.
Large concentrations of humans produce large concentrations of waste. Kitchen waste, broken objects, and similar material all need to be disposed of, while small numbers of people can dispose of their waste locally without encouraging vermin or endangering their health. Once people began to live together in large numbers, around five thousand years ago, such methods began to become impractical and material usually was brought into these new settlements but would rarely be taken out again.
Urban archaeology can be applied to the study of social, racial, and economic dynamics and history within contemporary and antiquated cities as well as the environmental impacts within these spaces. [1]
Up until the nineteenth century when organized rubbish disposal became widespread in urban areas people invariably threw their waste from their windows or buried it in their gardens. If their houses fell down, a common enough occurrence when planning laws were non-existent, owners would pick out what they could reuse, stamp down the remains and rebuild on the old site. Archaeological excavations of urban sites are often categorized by these remains and as well as the former impacts of modern technology such as sanitation, commercial, or transportation services [2]
The effect of this is that even a moderately sized settlement of any antiquity is built on top of a heap of refuse and demolished buildings and is therefore raised up from its original height on a plateau of archaeology. This is most apparent in the tel sites of the Near East where towns that have been occupied for thousands of years are raised up many metres above the surrounding landscape.
In walled towns, such as those in medieval Europe, the effect of the encircling defenses was to hold in the waste so that it could not slip outwards, magnifying the effect.
Redevelopment and archaeological excavation is a part of modern urban life and public interest in urban archaeological work is often strong, [3] yet developers can be cautious of unbridled dissemination of information that has the potential to ignite public opinion. Urban archaeology carries the opportunity for archaeologists to work with the public to illustrate the history and heritage of discoveries.
Archaeological excavation within historic cities therefore often produces a thick stratigraphy dating back to the original foundation and telling the story of its history.
The City of London serves as an example, for urban excavations have been performed there since the late 1900s. These excavations, performed in populated areas of the city, revealed historical evidence of events unforeseen previously by historians. London sits on a tel, which preserves a layer of dark material, attributed to the burning of the city by Boudica in 60 AD. It was only by excavation of the urban areas that these revelations could be made, as the city has long since outgrown its borders after its rebuild, some years after the Boudican revolt.
Another good example is the City of Turku, founded in the Middle Ages in southwestern Finland, for which no reliable document has been preserved since its foundation; [4] countless excavations have been carried out in the city each year in order to gain more clarity on the city’s birth history. [5] [6] [7]
The dense stratigraphy of such cities posed problems for the archaeologists who first excavated them. Earlier excavations were generally limited to rural areas, or towns which had been long abandoned. Open area excavation was feasible as there was plenty of space and the archaeology could often be exposed just in plan. In working cities however, space for excavation is usually limited to the size of the open plot and one layer of archaeology needs to be excavated before the next one can be exposed.
Additionally, Rome was also a big archaeological site since it was considered well established and advanced over time. Many excavations have been done there and later studied by archaeologists. One archaeologist who spent great time studying Roman archaeology was W. F. Grimes.
Issues such as this had appeared before, at Pompeii or at multi-phase rural sites but the move towards the investigation of cities, which began in Europe following the Second World War. The trend of urban excavation in areas such as Europe, the East Coast of the United States, and other western world cities, has grown since the war. Due to the bombing of landscapes during the war, the possibility of losing evidence connected to early civilizations became realized. The idea of settlement follows a principle, that settlement is made where resources are conveniently accessed. Prosperous cities, such as Boston and London, began as settlements, and grew quickly due to the convenient access of resources. However, the fact that these cities still exist today does not dismiss the fact that, at some point in history, some other civilization had once settled there.
The resulting solution revolved around the method of single context recording. This method was started by Ed Harris and Patrick Ottaway in 1976 before being expanded upon by the Museum of London in the mid 1980s and transferred to the York Archaeological Trust. [8] The practice involves drawing each feature individually in plan and then relating its position to the site grid rather than planning large areas at once. Each drawing is made on a square piece of translucent film representing a 5-metre x 5-metre grid square. The site is excavated down to the first significant layer of archaeology and features excavated and recorded as normal but also planned as single contexts. The site is then reduced to the next layer of archaeology and the process begins again. The excavation and recording can continue until natural deposits are reached. A small, deep trench known as a sondage is often excavated at first to provide a view of the entire stratigraphy at once and give an indication of the quantity of material to be excavated. Simply put, if someone does one plan per context than the method that are using is single context recording. [8]
Once the work is finished, the square sheets can be overlaid onto one another to provide a picture of the site. By identifying which features cut others and using information from dateable artefacts and ecofacts an archaeologist can isolate various phases of activity and show how the use of the site developed of periods of hundreds or even thousands of years. Context record sheets produced by the individual excavators provide further information on each context's nature and relationship with its neighbours. Such interpretation would be impossible using open area excavation where numerous overall site plans would soon seem inflexible.
Dame Kathleen Mary Kenyon, was a British archaeologist of Neolithic culture in the Fertile Crescent. She led excavations of Tell es-Sultan, the site of ancient Jericho, from 1952 to 1958, and has been called one of the most influential archaeologists of the 20th century. She was Principal of St Hugh's College, Oxford, from 1962 to 1973, having undertaken her own studies at Somerville College, Oxford.
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years.
MOLA is an archaeology and built heritage practice and independent charitable company registered with the Chartered Institute for Archaeologists (CIfA), providing a wide range of professional archaeological services to clients in London and across the country. It is one of the largest archaeological service providers in the UK, and is the only one with IRO status.
In archaeology a section is a view in part of the archaeological sequence showing it in the vertical plane, as a cross section, and thereby illustrating its profile and stratigraphy. This may make it easier to view and interpret as it developed over time.
Prehistoric archaeology is a subfield of archaeology, which deals specifically with artefacts, civilisations and other materials from societies that existed before any form of writing system or historical record. Often the field focuses on ages such as the Stone Age, Bronze Age and Iron Age, although it also encompasses periods such as the Neolithic. The study of prehistoric archaeology reflects the cultural concerns of modern society by showing interpretations of time between economic growth and political stability. It is related to other disciplines such as geology, biology, anthropology, historiography and palaeontology, although there are noticeable differences between the subjects they all broadly study to understand; the past, either organic or inorganic or the lives of humans. Prehistoric archaeology is also sometimes termed as anthropological archaeology because of its indirect traces with complex patterns.
Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles. The concept derives from the geological use of the idea that sedimentation takes place according to uniform principles. When archaeological finds are below the surface of the ground, the identification of the context of each find is vital in enabling the archaeologist to draw conclusions about the site and about the nature and date of its occupation. It is the archaeologist's role to attempt to discover what contexts exist and how they came to be created. Archaeological stratification or sequence is the dynamic superimposition of single units of stratigraphy, or contexts.
In archaeology, survey or field survey is a type of field research by which archaeologists search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area. Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage.
The Harris matrix is a tool used to depict the temporal succession of archaeological contexts and thus the sequence of depositions and surfaces on a 'dry land' archaeological site, otherwise called a 'stratigraphic sequence'. The matrix reflects the relative position and stratigraphic contacts of observable stratigraphic units, or contexts. It was developed in 1973 in Winchester, England, by Edward C. Harris.
In archaeological excavation, a plan is a drawn record of features and artifacts in the horizontal plane.
The year 1954 in archaeology involved some significant events.
Aboa Vetus and Ars Nova is a museum in central Turku, Finland. The museum is housed in a building known as the Rettig palace, originally built in 1928. The archaeological section Aboa Vetus displays portions of the city dating back to medieval times, while Ars Nova is a museum of contemporary art.
The Wheeler–Kenyon method is a method of archaeological excavation. The technique originates from the work of Mortimer Wheeler and Tessa Wheeler at Verulamium (1930–35), and was later refined by Kathleen Kenyon during her excavations at Jericho (1952–58). The Wheeler–Kenyon system involves digging within a series of squares that can vary in size set within a larger grid. This leaves a freestanding wall of earth—known as a "balk"—that can range from 50 cm for temporary grids, and measure up to 2 metres in width for a deeper square. The normal width of a permanent balk is 1 metre on each side of a unit. These vertical slices of earth allow archaeologists to compare the exact provenance of a found object or feature to adjacent layers of earth ("strata"). During Kenyon's excavations at Jericho, this technique helped discern the long and complicated occupational history of the site. It was believed that this approach allowed more precise stratigraphic observations than earlier "horizontal exposure" techniques that relied on architectural and ceramic analysis.
Single context recording was initially developed by Ed Harris and Patrick Ottaway in 1976, from a suggestion by Laurence Keen. It was further developed by the Department of Urban Archaeology from where it was then exported, in the mid-1980s by Pete Clarke to the Scottish Urban Archaeological Trust and Nick Pearson to the York Archaeological Trust. It has become a popular system of recording and planning being used in many countries in Europe and in Lebanon, it is especially suited to the complexities of deep, typically urban, archaeology. Each excavated context is given a unique "context number" and is recorded by type on a context sheet and perhaps being drawn on a plan and/or a section. Depending on time constraints and importance contexts may also be photographed, but in this case a grouping of contexts and their associations are the purpose of the photography. Finds from each context are bagged and labelled with their context number and site code for later cross-reference work carried out post excavation. The height above sea level of pertinent points on a context, such as the top and bottom of a wall are taken and added to plans sections and context sheets. Heights are recorded with a dumpy level or total station by relation to the site temporary benchmark. Samples of deposits from contexts are sometimes also taken, for later environmental analysis or for scientific dating.
In the field of archaeology, a spit is a unit of archaeological excavation with an arbitrarily assigned measurement of depth and extent. It is a method of excavation employed without regard to the archaeological stratigraphy that may be identifiable at the archaeological site under investigation. The method of excavating in arbitrary spits is most frequently encountered at site excavations which lack any visible or reconstructable stratigraphy in the archaeological context, or when excavating through intrusive or fill deposits.
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology, history or geography.
Martin Biddle, is a British archaeologist and academic. He is an emeritus fellow of Hertford College, Oxford. His work was important in the development of medieval and post-medieval archaeology in Great Britain.
Tell Yunatsite, also known as Ploskata mogila, is situated in the Pazardzhik Province of southern Bulgaria, some 8 kilometres (5 mi) to the west of the district capital Pazardzhik. The tell stands 12 metres (39 ft) above modern ground level and has a diameter of 110 m (360 ft). It is situated on a low terrace at the right bank of the former Topolnitsa riverbed near to its confluence with the Maritsa River. Medieval, Roman, Iron Age, Early Bronze Age, and Copper Age periods have all been attested at the site. The Copper Age tell is associated with the Karanovo culture.
