Metlika Castle is located above the old part of the town of Metlika, very near the Croatian border. The castle was first mentioned in written sources in 1456. During the Ottoman incursions in the 15th and 16th century, it was owned by the Counts of Alap, and it played a key role in defense against the Turks. Later, the castle was owned by the house of Frankopan, and later yet by the chapterhouse of the bishopric of Zagreb.
During the 18th century, the castle was damaged by fire twice (in 1705 and 1790); after repairs it was bought by Jožef Savinšek in 1792. It survived World War II intact and was afterward nationalized without compensation and converted into the headquarters of the Museum of White Carniola, established in 1951, and became home to some of its permanent collections. Exhibits include a cultural history of White Carniola, collections of Roman and medieval stone markers and memorials, and an ethnological collection on the historical way of life in White Carniola. The former castle stables and other outbuildings house the Metlika Slovene Firefighting Museum. In addition, the second floor contains a wedding hall, and the basement a wine cellar. Metlika Castle also features the Gangl Gallery for temporary exhibitions, which is part of Museum of White Carniola.
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.
