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 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.
