Skalka Castle was built in the early 14th century. The first proven owner was Petr von Skalka between 1357 and 1360. In 1418, Skalken came to Hans von Sullowitz and remained in the possession of the noble family Cappleri de Sulewicz until 1540. In 1639 the Swedes burned the castle and it was not rebuilt.
At the end of the 17th century, Jan Hrzán von Harras built a Baroque palace at the foot of the castle rock. The building material was obtained from the decaying castle, so that today, apart from the picturesque keep, which is not accessible, no other remains of the castle complex are preserved. Inside the tower, which last served as a hunger tower, inscriptions from the 17th century by prisoners have been found.
After the expropriation of the Schönborns, the castle served as a storage facility for the Litoměřice State Regional Archives from 1945 . In 1959 some repairs were made to the building. The castle has been owned by the Vlastislav Municipality since 2001. After repairs have been carried out, the second floor can be used for exhibitions and cultural events. The ground floor and first floor are in poor structural condition; security measures will continue to be carried out on the building fabric. The interior of the castle has not been preserved.
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.
