Astino Abbey was founded around 1070 by a group of members of the Vallumbrosan Order led by John Gualbert during a time in which, through reforms, clerics were trying to revive the Catholic Church's position.
The Romanesque church and the first conventual buildings were built by Bertario, the first abbot, who supervised the abbey for 21 years until 1128.
The monastery was suppressed on 4 July 1797 by the ciil aurhorities of Bergamo. Its assets were given to the nearby hospital, founded and previously run by the monks.
In 1832 the site was put to use as a psychiatric hospital, which it remained until 1892. It was then used for agricultural purposes, and was sold to private buyers in 1923.
In 1973 the property was acquired by a private company for conversion into a golfing centre, but the plan ran into so much opposition that it never came to fruition, and the monastery buildings have been left neglected until 2015.
The Church of Santo Sepulchro was consecrated in 1117, but has been rebuilt over the centuries. The base of the bell-tower dates to the 12th-century, but now has a baroque superstructure atop. The building includes a cloister of the 15th century and a chapel to the memory of Blessed Guallo de Roniis, exiled bishop of Brescia.
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.
