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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
