This is a list of monoliths organized according to the size of the largest block of stone on the site. A monolith is a large stone which has been used to build a structure or monument, either alone or together with other stones. In this list at least one colossal stone over ten tons has been moved to create the structure or monument.
In most cases ancient civilizations had little, if any, advanced technology that would help them move these monoliths.[ citation needed ] The most notable exception is that of the Ancient Egyptians, ancient Greeks and Romans, who had cranes and treadwheels to help lift colossal stones (see list of ancient Greek and Roman monoliths).
This article also includes a list of modern experimental archaeology efforts to move colossal stones using technologies available to the respective ancient civilizations.
Most of these weights are based on estimates by published scholars; however, there have been numerous false estimates of many of these stones presented as fact. To help recognize exaggerations, an introductory description shows how to calculate the weight of colossal stones from first principles.
In the cases of smaller monoliths it may be possible to weigh them. However, in most cases monoliths are too large or they may be part of an ancient structure so this method cannot be used. The weight of a stone can be calculated by multiplying its volume and density. Each of these presents challenges.
To obtain accurate estimates, one needs to survey the monolith, including realistic and explicit assessment of the shapes of inaccessible portions, and then calculate the volume and estimate volumetric errors, which vary crudely as the cube of linear uncertainties.
The density of most stone is between 2 and 3 tons per cubic meter. Basalt weighs about 2.8 to 3.0 tons per cubic meter; granite averages about 2.75 metric tons per cubic meter; limestone, 2.7 metric tons per cubic meter; sandstone or marble, 2.5 tons per cubic meter. [1] [2] [3] [4] [5] Some softer stones may be lighter than 2 tons per cubic meter; for example, volcanic tuff or some types of sandstone weigh about 1.9 tons per cubic meter. [6] [7] [8] Since the density of most of these stones varies, it is necessary to know the source of the stone to obtain accurate measurements. [9] [10] Identifying the rock type alone is not sufficient, as this table [11] illustrates:
Material | Density |
---|---|
Sediments | 1.7–2.3 |
Sandstone | 1.9–2.7 [8] |
Shale | 2.0–2.7 |
Limestone | 2.5–2.8 |
Granite | 2.5–2.8 |
Metamorphic rock | 2.6–3.0 |
Basalt | 2.7–3.1 |
Simply identifying the monolith as sandstone would allow a ± 15% uncertainty in the weight estimate. In practice, one would measure the density of the monolith itself, and preferably document any variation in density within the monolith, as it may not be homogeneous. Non-destructive methods of density measurements are available (e.g., electron back-scatter); alternatively, the site may contain already-separated fragments of the monolith which can be used for laboratory measurements or on-site techniques. At the crudest, a weighing device and a bucket can obtain two significant figures for a density value.
This section lists monoliths that have been at least partially quarried but not moved.

Roman column monuments like Trajan's Column, though not often themselves monolithic, were built using very large sculpted stone blocks, stacked atop one another using cranes and lewises. The capital block of the column was usually even larger and heavier than the column drums. The columns of Marcus Aurelius, Antoninus Pius, and Constantine, and the lost columns of Theodosius, Arcadius, and Leo were all constructed in this way, on monumental pedestals and crowned with colossal statues. A few were monoliths, including the Column of Diocletian in Alexandria, called "Pompey's Pillar", the "Column of the Goths" and the Column of Marcian in Constantinople, and the lost Column of Antoninus Pius in Rome.

The Great Pyramid of Giza is the largest Egyptian pyramid. It served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom. Built c. 2600 BC, over a period of about 26 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northeastern end of the line of the three main pyramids at Giza.
An obelisk is a tall, slender, tapered monument with four sides and a pyramidal or pyramidion top. Originally constructed by Ancient Egyptians and called tekhenu, the Greeks used the Greek term obeliskos to describe them, and this word passed into Latin and ultimately English. Though William Thomas used the term correctly in his Historie of Italie of 1549, by the late sixteenth century, Shakespeare failed to distinguish between pyramids and obelisks in his plays and sonnets. Ancient obelisks are monolithic and consist of a single stone; most modern obelisks are made of several stones.
The pyramid of Djoser, sometimes called the Step Pyramid of Djoser, is an archaeological site in the Saqqara necropolis, Egypt, northwest of the ruins of Memphis. It is the first pyramid to be built. The 6-tier, 4-sided structure is the earliest colossal stone building in Egypt. It was built in the 27th century BC during the Third Dynasty for the burial of Pharaoh Djoser. The pyramid is the central feature of a vast mortuary complex in an enormous courtyard surrounded by ceremonial structures and decoration.
In ancient Egyptian history, the Old Kingdom is the period spanning c. 2700–2200 BC. It is also known as the "Age of the Pyramids" or the "Age of the Pyramid Builders", as it encompasses the reigns of the great pyramid-builders of the Fourth Dynasty, such as King Sneferu, under whom the art of pyramid-building was perfected, and the kings Khufu, Khafre and Menkaure, who commissioned the construction of the pyramids at Giza. Egypt attained its first sustained peak of civilization during the Old Kingdom, the first of three so-called "Kingdom" periods, which mark the high points of civilization in the lower Nile Valley.
The Karnak Temple Complex, commonly known as Karnak, comprises a vast mix of temples, pylons, chapels, and other buildings near Luxor, Egypt. Construction at the complex began during the reign of Senusret I in the Middle Kingdom and continued into the Ptolemaic Kingdom, although most of the extant buildings date from the New Kingdom. The area around Karnak was the ancient Egyptian Ipet-isut and the main place of worship of the 18th Dynastic Theban Triad, with the god Amun as its head. It is part of the monumental city of Thebes, and in 1979 it was added to the UNESCO World Heritage List along with the rest of the city. Karnak gets its name from the nearby, and partly surrounded, modern village of El-Karnak, 2.5 kilometres north of Luxor.
The Museum of Egyptian Antiquities, commonly known as the Egyptian Museum, located in Cairo, Egypt, houses the largest collection of Egyptian antiquities in the world. It houses over 120,000 items, with a representative amount on display. Located in Tahrir Square in a building built in 1901, it is the largest museum in Africa. Among its masterpieces are Pharaoh Tutankhamun's treasure, including its iconic gold burial mask, widely considered one of the best-known works of art in the world and a prominent symbol of ancient Egypt.
A megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. There are over 35,000 structures or arrangements in Europe alone, located widely from Sweden to the Mediterranean sea.
The Ramesseum is the memorial temple of Pharaoh Ramesses II. It is located in the Theban Necropolis in Upper Egypt, on the west of the River Nile, across from the modern city of Luxor. The name – or at least its French form Rhamesséion – was coined by Jean-François Champollion, who visited the ruins of the site in 1829 and first identified the hieroglyphs making up Ramesses's names and titles on the walls. It was originally called the House of millions of years of Usermaatra-setepenra that unites with Thebes-the-city in the domain of Amon.Usermaatra-setepenra was the prenomen of Ramesses II.
The Colossi of Memnon are two massive stone statues of the Pharaoh Amenhotep III, which stand at the front of the ruined Mortuary Temple of Amenhotep III, the largest temple in the Theban Necropolis. They have stood since 1350 BC, and were well known to ancient Greeks and Romans, as well as early modern travelers and Egyptologists. The statues contain 107 Roman-era inscriptions in Greek and Latin, dated to between AD 20 and 250; many of these inscriptions on the northernmost statue make reference to the Greek mythological king Memnon, whom the statue was then – erroneously – thought to represent.
Sacsayhuamán or Saksaywaman is a citadel on the northern outskirts of the city of Cusco, Peru, the historic capital of the Inca Empire. The site is at an altitude of 3,701 metres (12,142 ft).
The Bronze Horseman is an equestrian statue of Peter the Great in the Senate Square in Saint Petersburg, Russia. It was opened to the public on 7 (18) August 1782. Commissioned by Catherine the Great, it was created by the French sculptor Étienne Maurice Falconet. The statue influenced a 1833 poem of the same name by Alexander Pushkin, which is widely considered one of the most significant works of Russian literature. The statue is now one of the symbols of Saint Petersburg.
Spanning over three thousand years, ancient Egypt was not one stable civilization but in constant change and upheaval, commonly split into periods by historians. Likewise, ancient Egyptian architecture is not one style, but a set of styles differing over time but with some commonalities.
The construction of the Egyptian pyramids can be explained with well-established scientific facts, however there are some aspects that are even today considered controversial hypotheses. The construction techniques used seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. Most of the construction hypotheses are based on the belief that huge stones were carved from quarries with copper chisels, and these blocks were then dragged and lifted into position. Disagreements chiefly concern the methods used to move and place the stones.
Ancient Egyptian technology describes devices and technologies invented or used in Ancient Egypt. The Egyptians invented and used many simple machines, such as the ramp and the lever, to aid construction processes. They used rope trusses to stiffen the beam of ships. Egyptian paper, made from papyrus, and pottery were mass-produced and exported throughout the Mediterranean Basin. The wheel was used for a number of purposes, but chariots only came into use after the Second Intermediate Period. The Egyptians also played an important role in developing Mediterranean maritime technology including ships and lighthouses.
The Younger Memnon is an Ancient Egyptian statue, one of two colossal granite statues from the Ramesseum mortuary temple in Thebes, Upper Egypt. It depicts the Nineteenth Dynasty Pharaoh Ramesses II wearing the Nemes head-dress with a cobra diadem on top. The damaged statue has since been separated from its upper torso and head. These sections can now be found in the British Museum. The remainder of the statue remains in Egypt. It is one of a pair that originally flanked the Ramesseum's doorway. The head of the other statue is still found at the temple.
Pompey's Pillar is a Roman triumphal column in Alexandria, Egypt. Despite its modern name, it was actually set up in honour of the Roman emperor Diocletian between 298–302 AD. The giant Corinthian column originally supported a colossal porphyry statue of the emperor in armour. It stands at the eastern side of the temenos of the Serapeum of Alexandria, which is now in ruins.
The Baalbek Stones are six massive Roman worked stone blocks in Baalbek, Lebanon, characterised by a megalithic gigantism unparallelled in antiquity.
The Olmec colossal heads are stone representations of human heads sculpted from large basalt boulders. They range in height from 1.17 to 3.4 metres. The heads date from at least 900 BC and are a distinctive feature of the Olmec civilization of ancient Mesoamerica. All portray mature individuals with fleshy cheeks, flat noses, and slightly-crossed eyes; their physical characteristics correspond to a type that is still common among the inhabitants of Tabasco and Veracruz. The backs of the monuments are often flat.
The Temple of Jupiter is a colossal Roman temple, the largest of the Roman world after the Temple of Venus and Roma in Rome. It is situated at the Baalbek complex in Baalbek, Lebanon, It is unknown who commissioned or designed the temple, nor exactly when it was constructed. It is situated at the western end of the Great Court of Roman Heliopolis, on a broad platform of stone raised another 7 m (23 ft) above the huge stones of the foundation, three of which are among the heaviest blocks ever used in a construction. Cultic activity had long taken place at the site; the temple presumably replaced an earlier one, possibly using the same foundation.
