Saint Paul's Abbey in Lavanttal is a Benedictine monastery established in 1091 by the Sponheim count Engelbert I, Margrave of Istria. It was built on the site of a former castle and a church consecrated by Archbishop Hartwig of Salzburg in 991.
Backed by subsidies from Hirsau Abbey as well as by Engelbert's brother Archbishop Hartwig of Magdeburg, the monastery quickly prospered and with its own scriptorium and a grammar school evolved to the most significant Abbey in Carinthia. Pope Urban II put it unter papal protection in 1099 and prevented the development to a proprietary monastery of the Sponheim dynasty.
During the 15th century conflict of the Habsburg duke Frederick III with the Counts of Celje, the troops of Count Ulrich II devastated the premises. The abbey was again ravaged by Ottoman forces in 1476 and besieged by the Hungarian king Matthias Corvinus in 1480. In the beginning Ottoman–Habsburg wars, the Habsburg rulers increasingly encumbered the monastery with tributes, they rivalled with the Prince-Archbishops of Salzburg to exert influence, while the conventual life decayed. In the 16th century, large parts of Carinthia turned Protestant and two abbots were declared deposed by Archduke Charles II of Inner Austria.
The resurgence of St. Paul's began under Hieronymus Marchstaller, abbot from 1616. The derelict premises around the monastery church were rebuilt according to plans modelled on the Spanish Escorial. The reconstruction was completed under Marchstaller's successors until 1683.
The abbey was dissolved in 1782 by decree of Emperor Joseph II, but resettled in 1809 with monks descending from St. Blaise Abbey in the Black Forest.
Within the abbey precinct there is a Romanesque basilica dating from the end of the 12th century. After a fire in 1367 a Gothic vaulted ceiling was added, painted with 44 frescoes by the Tyrolean masters Friedrich and Michael Pacher.
The interior decoration of the church by the Styrian artist Philipp Jakob Straub dates from the 18th century. Beneath the Baroque high altar is a crypt, in which are the coffins of 13 members of the Habsburg family.
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.
