Säben Abbey was established in 1687, when it was first settled by the nuns of Nonnberg Abbey in Salzburg. Situated on the 'holy mountain', Säben was for centuries a centre of pilgrimage and controlled an extensive religious precinct. On the site of the present nunnery there was an earlier Roman settlement. Between the 6th century and about 960 there was a bishopric (episcopatus Sabiona) seated here. The church 'im Weinberg' dates from that time and its remains have been excavated along with a large burial ground in recent times.
Säben later became a fortress of the bishops. In the 14th and 15th centuries Säben Castle was the seat of the judges of Klausen and the centre of administration of the southern territories of the Diocese of Brixen.
A community of Benedictine nuns was established here in 1686 by the local priest, in premises at the foot of the mountain. The abbey church was dedicated by Johann Franz, Count Khuen von Belasi, then Bishop of Brixen.
Although the nunnery was repeatedly looted during the Napoleonic wars and stripped of its assets during the secularization in 1803, the community survived although in an impoverished state through the 19th century until it gradually revived from about 1880, when, during the period of the Kulturkampf in Germany (1871–1878), the monks of Beuron Abbey were in exile in the county of Tyrol and were in contact with the nuns at Säben. At this time new premises were built in the ruins of the castle on the mountain. The nuns of Säben adopted the Beuronese mode of life, although the abbey was formally accepted into the Beuronese Congregation of the Benedictine Confederation only in 1974.
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.
