The Baumkircher Tower, also known as Tabor Castle, is a defensive tower or small castle located in the town of Vipava. The tower was built by Herhlin Kranspergar in 1342, as a fortification guarding the adjacent stone bridge across the Vipava River. In 1386, the knight Haertl sold it to Hermann I of Celje After passing from their hands to the Patriarchate of Aquileia to the Habsburgs, it was given in fief to the knights Baumkircher, who lent it its current name. The family retained it until 1471, when then-owner Andreas Baumkircher instigated a revolt of the Styrian nobility against Holy Roman Emperor Frederick III, and was beheaded for treason in Graz.
The castle then reverted to the duchy of Carniola, and was managed by its officers and leaseholders. The latter included Jurij Gallo, who between 1517-1521 subleased the tower to Carniolan vicedom (bishop's deputy in secular affairs) Erasmus Braunwart.
From either 1533 or 1624 to the end of World War I, the castle was a possession of the Lanthieri family.
The preserved elements of the structure include a part of the old main building, the defensive tower, and a partial wall with a gateway and a stone relief of the Lanthieri arms, dated 1653, set above the portal.
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.
