The commandery of Saint-Jean-d'Acre is a monumental complex founded by the Hospitallers. From the first years of the establishment of the Crusaders in the city, the Hospitallers received donated properties. In 1110, King Baldwin granted the permission to them to keep the buildings located to the north of the Sainte-Croix church. In the years 1130, the buildings were damaged during works near the church and the Hospitallers decided to move near the 12th century north wall of the city. This is the actual place of the commandery.
In 1149, the first testimony of the commandery is in a document concerning the construction of the Saint-Jean church. In 1169, a pilgrim described the commandery of the Hospitallers of Acre as a very impressive fortified building.
After the defeat of Hattin in 1187, Saladin took the city. In 1191, during the third Crusade, the Frankish reconquer Acre after its siege. The Hospitallers moved back in their buildings. Jerusalem is no longer in the hands of the crusaders. And so the commandery becomes the new headquarters of the order. A new construction campaign took place between the end of 12th century and 13th century with new wings and additional floors.
The courtyard has an area of 1200 m2 and is surrounded by a series of arcades. On the east side, a staircase leads to the upper parts. A well with a depth of 4.5 m is located near the north side and two shallow pools are next to this well. On the south side a pool with a depth of 1.5 m and another well were built.
The north wing was built along the north wall. There are ten vaulted rooms ten meters high built during the Frankish era. The exterior wall is massive with a thickness of 3.5 m. Later to the west, two new rooms will complete this building. In the south wall, there are windows that overlook a narrow passage and the wall of the pillar room. The entrance of the building is in the south side wall.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
