Tiglieto Abbey, founded in 1120, was the first Cistercian abbey to be founded in Italy, and also the first outside France. It was a daughter house of La Ferté Abbey. The first abbot was probably Opizzone. It may have gained the name Tiglieto after being given the estate of that name by the Margrave Anselm of Ponsone in 1131.
In 1442, through Pope Eugenius IV, Tiglieto became an abbey in commendam. In 1648 it was turned into a family estate of the last commendatory abbot, Cardinal Raggio, and dissolved. In 1747 the area was occupied by the Austrians, who shortly afterwards were driven out by the Genoese. In 2000 Tiglieto was reoccupied by the Cistercians.
The church is a primitive Romanesque brick basilica; the original side-chapels were removed in the 14th century to make way for a new east end. The nave was vaulted in the Baroque period, and a new choir at the west end was added at the same time, as was a Baroque campanile.
The conventual buildings are to the south of the church. The early Gothic chapter house in the east range has survived, with a square chapter room with nine bays from the early 13th century and symmetrical triforium windows looking onto the central courtyard and the site of the cloister, no longer extant, with the dormitory with bricked-up windows in the upper storey, as have the sacristy, the Fraternei and to the south the refectory building, as well as the lay brothers' block in the west, now converted for residential purposes.
The entire precinct was renovated for the new community that took over the premises in 2000.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
