Solomon's Stables was an underground vaulted space now used as a Muslim prayer hall at the bottom of stairs which lead down from the al-Aqsa Mosque, under the Temple Mount, to the base of the southern wall of the Temple Mount. Solomon's Stables are located under the southeastern corner of the Temple Mount, 12½ metres below the courtyard and feature twelve rows of pillars and arches. In December 1996 the Jerusalem Islamic Waq (an Islamic religious trust) converted the area into a prayer hall by adding lights and floor tiles, and renamed it the Marwani Prayer Hall.
The structure is most widely said to have been built by King Herod as part of his extension of the platform of the Temple Mount southward onto the Ophel. The Herodian engineers constructed the enormous platform as a series of vaulted arches in order to reduce pressure on the retaining walls. These vaults were originally storage areas of the Second Temple. A great deal of the original interior survives in the area of the Herodian staircases, although not in the area now renovated for use as a mosque. Visitors are rarely permitted to enter the areas with Herodian finishes.
The underground space for the most part remained empty except for the Crusaders period. The Crusaders converted it in 1099 into a stable for the cavalry. The rings for tethering horses can still be seen on some of the pillars. The structure has been called Solomon's Stables since Crusader times as a historical composite. 'Solomon's' refers to the First Temple built on the site, while the 'stables' refers to the functional usage of the space by the Crusaders in the time of Baldwin II (King of Jerusalem 1118-1131 CE).References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
