The Western Stone is a monolithic ashlar (worked stone block) forming part of the lower level of the Western Wall in Jerusalem. This largest stone in the Western Wall is visible within the Western Wall Tunnel. [1] It is one of the largest building blocks in the world. [2]
The stone's exposed face can be freely measured and is 13.55 metres (44.5 ft) long and 3.3 metres (11 ft) high, [1] but its width, or depth, is hidden within the wall.
In June 2006, Harry M. Jol, from the University of Wisconsin–Eau Claire, performed measurements with ground-penetrating radar (GPR) to determine the depth of the stone. The conclusion of his team was that its depth ranges from approximately 1.8 to 2.5 metres (5.9 to 8.2 ft). [3] [4] Prior estimates ranged up to 16.5m.
The calculated weight of the stone block is of 250–300 tonnes, based on Jol's measurement. [4] Prior to the Jol's GPR measurement, the stone was estimate dto weight between 550 and 600 tonnes. [5] [6]
A previous estimate of the stone's depth was 16.5 metres (54 ft), a multiple of the GPR measurement, and led to a calculated total weight of 567 tonnes.; Other pre-2006 sources circulated similar figures, namely 550 to 600 tonnes. [5] [6] The Western Wall Heritage Foundation (WWHF) website indicates, as of March 2020, an estimated depth of 2–4.6 metres (6.6–15.1 ft), with an estimated weight of "several hundred tons", [1] thus moderating its former estimated weight of 517 tonnes (570 short tons); [7]
The stone is located in a section of the Western Wall (in the broader meaning of the term) north of Wilson's Arch, below ground level, and can be accessed through the Western Wall tunnels. It is part of the "Great Course", a name used by the WWHF for the tallest and longest course (layer of stones) of the Western Wall. [1] Its stone blocks are of Herodian age, and the stones next to the Western Stone are, in sequence, 2 metres (6.6 ft), 12.12 metres (39.8 ft), and 8 metres (26 ft) long, respectively. [1]
Masada is an ancient fortification in southern Israel, situated on top of an isolated rock plateau, akin to a mesa. It is located on the eastern edge of the Judaean Desert, overlooking the Dead Sea 20 km (12 mi) east of Arad.
The Western Wall, known in the West as the Wailing Wall, and in Islam as the Buraq Wall, is a portion of ancient limestone wall in the Old City of Jerusalem that forms part of the larger retaining wall of the hill known to Jews and Christians as the Temple Mount. Just over half the wall's total height, including its 17 courses located below street level, dates from the end of the Second Temple period, and is believed to have been begun by Herod the Great. The very large stone blocks of the lower courses are Herodian, the courses of medium-sized stones above them were added during the Umayyad period, while the small stones of the uppermost courses are of more recent date, especially from the Ottoman period.
The Golden Gate or Gate of Mercy is the only eastern gate of the Temple Mount, and one of only two Gates of the Old City of Jerusalem that used to offer access into the city from the East side.
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. This nondestructive method uses electromagnetic radiation in the microwave band of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks.
The Tower of David, also known as the Citadel, is an ancient citadel located near the Jaffa Gate entrance to the Old City of Jerusalem.
The Tunnel of Eupalinos or Eupalinian aqueduct is a tunnel of 1,036 m (3,399 ft) length running through Mount Kastro in Samos, Greece, built in the 6th century BC to serve as an aqueduct. The tunnel is the second known tunnel in history which was excavated from both ends, and the first with a geometry-based approach in doing so. Today it is a popular tourist attraction. The tunnel is inscribed on the UNESCO World Heritage List along with the nearby Pythagoreion and Heraion of Samos, and it was designated as an International Historic Civil Engineering Landmark in 2017.
The Western Wall Tunnel is a tunnel exposing the Western Wall slightly north from where the traditional, open-air prayer site ends and up to the Wall's northern end. Most of the tunnel is in continuation of the open-air Western Wall and is located under buildings of the Muslim Quarter of the Old City of Jerusalem. While the open-air portion of the Western Wall is approximately 60 metres (200 ft) long, the majority of its original length of 488 metres (1,601 ft) is hidden underground. The tunnel allows access to the remainder of the Wall in a northerly direction.
The Temple Mount, a holy site in the Old City of Jerusalem, also known as the al-Ḥaram al-Sharīf or Al-Aqsa, contains twelve gates. One of the gates, Bab as-Sarai, is currently closed to the public but was open under Ottoman rule. There are also six other sealed gates. This does not include the Gates of the Old City of Jerusalem which circumscribe the external walls except on the east side.
Meleke, also transliterated melekeh or malaki, is a lithologic type of white, coarsely-crystalline, thickly bedded-limestone found in the Judaean Mountains in Israel and the State of Palestine. It has been used in the traditional architecture of Jerusalem since ancient times, especially in Herodian architecture. Though it is often popularly referred to as Jerusalem stone, that phrase can refer to a number of different types of stone found and used in or associated with Jerusalem.
Herodian architecture is a style of classical architecture characteristic of the numerous building projects undertaken during the reign of Herod the Great, the Roman client king of Judea. Herod undertook many colossal building projects, most famously his reconstruction of the Temple in Jerusalem. Many of his structures were built upon comparable, previous Hasmonean buildings and most of his have, in their turn, vanished as well.
A number of archaeological excavations at the Temple Mount—a celebrated and contentious religious site in the Old City of Jerusalem—have taken place over the last 150 years. Excavations in the area represent one of the more sensitive areas of all archaeological excavations in Jerusalem.
The Hasmonean Baris was a citadel constructed north of Jerusalem's Temple Mount in existence during the Hasmonean period.
Robinson's Arch is the name given to a monumental staircase carried by an unusually wide stone arch, which once stood at the southwestern corner of the Temple Mount. It was built as part of the expansion of the Second Temple initiated by Herod the Great at the end of the 1st century BCE. Recent findings suggest that it may not have been completed until at least 20 years after his death. The massive stone span was constructed along with the retaining walls of the Temple Mount. It carried traffic up from ancient Jerusalem's Lower Market area and over the Tyropoeon street to the Royal Stoa complex on the esplanade of the Mount. The overpass was destroyed during the First Jewish–Roman War, only a few decades after its completion.
The Baalbek Stones are six massive Roman worked stone blocks in Baalbek, Lebanon, characterised by a megalithic gigantism unparallelled in antiquity.
The Southern Wall is the retaining wall of the Temple Mount at the southern end. It was built during King Herod's expansion of the Temple Mount platform southward on to the Ophel.
The Royal Stoa was an ancient basilica constructed by Herod the Great during his renovation of the Temple Mount at the end of the first century BCE. Probably Herod's most magnificent secular construction, the three-aisled structure was described by Josephus as deserving "to be mentioned better than any other under the sun." A center of public and commercial activity, the Royal Stoa was the likely location of Jesus' cleansing of the Temple recounted in the New Testament. The Royal Stoa overlooked Jerusalem's residential and commercial quarters, and at its southwestern corner was the place from which a ram's horn was blown to announce the start of holy days.
The Struthion Pool, effectually translated from the Greek as 'Sparrow Pool' is a large cuboid cistern beneath the Convent of the Sisters of Zion in the Old City of Jerusalem, built by Herod the Great in the first century BCE.
Wilson's Arch is the modern name for an ancient stone arch in Jerusalem, the first in a row of arches that supported a large bridge connecting the Herodian Temple Mount with the Upper City on the opposite Western Hill. The Arch springs from the Western Wall and is still visible underneath later buildings set against the Wall. The name Wilson's Arch is also used to denote the hall that it partially covers, which is currently used as a synagogue. This hall opens towards the Western Wall Plaza at the Plaza's northeast corner, so that it appears on the left of the prayer section of the Western Wall to visitors facing the Wall.
Dan Bahat is an Israeli archaeologist especially known for his excavations in Jerusalem, particularly at the Western Wall tunnels.
