Medieval fortification refers to medieval military methods that cover the development of fortification construction and use in Europe, roughly from the fall of the Western Roman Empire to the Renaissance. During this millennium, fortifications changed warfare, and in turn were modified to suit new tactics, weapons and siege techniques.
Lumber is wood that has been processed into uniform and useful sizes, including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing. Lumber has many uses beyond home building. Lumber is referred to as timber in the United Kingdom, Europe, Australia, and New Zealand, while in other parts of the world the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut.
A basement or cellar is one or more floors of a building that are completely or partly below the ground floor. Especially in residential buildings, it often is used as a utility space for a building, where such items as the furnace, water heater, breaker panel or fuse box, car park, and air-conditioning system are located; so also are amenities such as the electrical system and cable television distribution point. In cities with high property prices, such as London, basements are often fitted out to a high standard and used as living space.
A barrel vault, also known as a tunnel vault, wagon vault or wagonhead vault, is an architectural element formed by the extrusion of a single curve along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design. The barrel vault is the simplest form of a vault: effectively a series of arches placed side by side. It is a form of barrel roof.
A blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force or cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt.
A dugout or dug-out, also known as a pit-house or earth lodge, is a shelter for humans or domesticated animals and livestock based on a hole or depression dug into the ground. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. These structures are one of the most ancient types of human housing known to archaeologists, and the same methods have evolved into modern "earth shelter" technology.
An earth lodge is a semi-subterranean building covered partially or completely with earth, best known from the Native American cultures of the Great Plains and Eastern Woodlands. Most earth lodges are circular in construction with a dome-like roof, often with a central or slightly offset smoke hole at the apex of the dome. Earth lodges are well-known from the more-sedentary tribes of the Plains such as the Hidatsa, Mandan, and Arikara, but they have also been identified archaeologically among sites of the Mississippian culture in the eastern United States.
A root cellar, fruit cellar or earth cellar is a structure, usually underground or partially underground, used for storage of vegetables, fruits, nuts, or other foods. Its name reflects the traditional focus on root crops stored in an underground cellar, which is still often true; but the scope is wider, as a wide variety of foods can be stored for weeks to months, depending on the crop and conditions, and the structure may not always be underground.
The architecture of ancient Sri Lanka displays a rich diversity, varying in form and architectural style from the Anuradhapura Kingdom through the Kingdom of Kandy (1469–1815). Sinhalese architecture also displays many ancient North Indian influences. Buddhism had a significant influence on Sri Lankan architecture after it was introduced to the island in the 3rd century BC, and ancient Sri Lankan architecture was mainly religious, with more than 25 styles of Buddhist monasteries. Significant buildings include the stupas of Jetavanaramaya and Ruwanvelisaya in the Anuradhapura kingdom and further in the Polonnaruwa Kingdom. The palace of Sigiriya is considered a masterpiece of ancient architecture and ingenuity, and the fortress in Yapahuwa and the Temple of the tooth in Kandy are also notable for their architectural qualities. Ancient Sri Lankan architecture is also significant to sustainability, notably Sigiriya which was designed as an environmentally friendly structure.
British hardened field defences of World War II were small fortified structures constructed as a part of British anti-invasion preparations. They were popularly known as pillboxes, a reference to their shape.
Denghoog is a Neolithic passage grave dating from around 3000 BC on the northern edge of Wenningstedt-Braderup on the German island of Sylt. The name Denghoog derives from the Söl'ring Deng (Thing) and Hoog (Hill).
Bristol County Jail is a historic jail at 48 Court Street in Bristol, Rhode Island, and home to the Bristol Historical and Preservation Society.
A slab hut is a kind of dwelling or shed made from slabs of split or sawn timber. It was a common form of construction used by settlers in Australia and New Zealand during their nations' colonial periods.
Fewkes Group Archaeological Site, also known as the Boiling Springs Site, is a pre American history Native American archaeological site located in the city of Brentwood, in Williamson County, Tennessee. It is in Primm Historic Park on the grounds of Boiling Spring Academy, a historic schoolhouse established in 1830. The 15-acre site consists of the remains of a late Mississippian culture mound complex and village roughly dating to 1050-1475 AD. The site, which sits on the western bank of the Little Harpeth River, has five mounds, some used for burial and others, including the largest, were ceremonial platform mounds. The village was abandoned for unknown reasons around 1450. The site is named in honor of Dr. J. Walter Fewkes, the Chief of the Bureau of American Ethnology in 1920, who had visited the site and recognized its potential. While it was partially excavated by the landowner in 1895, archaeologist William E. Myer directed a second, more thorough excavation in October 1920. The report of his findings was published in the Bureau of American Ethnology's Forty-First Annual Report. Many of the artifacts recovered from the site are now housed at the Smithsonian Institution. It was added to the National Register of Historic Places on April 21, 1980, as NRIS number 80003880.
Kerala architecture is a style of architecture found in the Indian state of Kerala, and in parts of the Tulu Nadu region of Karnataka. Kerala's architectural style includes a unique Hindu temple architecture that emerged in southwestern India, and varies slightly from the Dravidian architecture observed in other parts of southern India. The architecture of Kerala is derived from the Indian Vedic architectural tradition and forms a part of Dravidian architecture, one of the three styles of temple mentioned in the ancient books on Vastu Shastra. The Tantrasamuchaya, Thachu-Shastra, Manushyalaya Chandrika, and Silparatna are all architectural treatises that have had an impact on the architecture of Kerala. The Manushyalaya Chandrika, a work devoted to domestic architecture, has its roots in Kerala.
Dally Castle is a ruined 13th-century stone motte-and-bailey fortress in Northumberland, and one of the first hall houses in Northumberland. It lies 5 miles (8.0 km) west of Bellingham Castle, and 4 miles (6.4 km) west of Bellingham on the Chirdon Burn, a tributary of the North Tyne. Dally Castle House was built in the 18th century next to the castle. Across the road lies a small flour mill used to grind wheat during the Napoleonic War.
The Green Bay Harbor Entrance Light is an offshore lighthouse near Green Bay, Wisconsin. Located 10 miles (16 km) from the mouth of the Fox River, it was erected to signal the entrance to Green Bay.
A turret was a small watch tower, incorporated into the curtain wall of Hadrian's Wall. The turrets were normally spaced at intervals of one third of a Roman mile between Milecastles, giving two Turrets between each Milecastle.
In fortification architecture, a rampart is a length of embankment or wall forming part of the defensive boundary of a castle, hillfort, settlement or other fortified site. It is usually broad-topped and made of excavated earth and/or masonry.
Castell Caer Seion is an Iron Age hillfort situated at the top of Conwy Mountain, in Conwy County, North Wales. It is unusual for the fact that the main fort contains a smaller, more heavily defended fort, complete with its own distinct defences and entrance, with no obvious means of access between the two. The construction date of the original fort is still unknown, but recent excavations have revealed evidence of occupation as early as the 6th century BC, whilst the smaller fort can be dated with reasonable certainty to around the 4th century BC. Whilst the forts were constructed in different periods, archaeologists have uncovered evidence of concurrent occupation, seemingly up until around the 2nd century BC. The larger fort contained around 50 roundhouses during its lifetime, whereas examinations of the smaller fort have turned up no more than six. The site was traditionally associated with Maelgwyn Gwynedd, but there is no evidence pointing to a 6th-century occupation. The fort and wider area beyond its boundaries have been said to retain significant archaeological potential, and are protected by law as a scheduled ancient monument.
