Kalec Castle is a partially ruined castle near Zagorje in Slovenia. The castle, of which only a single tower and some sections of wall survive intact, stands on slope known as Breg, near the source of the Pivka River, at an elevation of 618 m.
Illustrated in Valvasor's 1689 Glory of the Duchy of Carniola, it was built in the mid-17th century by the noble house of Steinberg. Its later owners included the Auersperg family and the Slovene composer Miroslav Vilhar, who also died in it. The castle was abandoned by its last residents after World War I, and began falling apart.
In 1941 it hosted a meeting of the antifascist militant group TIGR.
Today the Krpan Hiking Trail passes beside the ruins, which are surrounded by a copse of old linden trees. The path to the castle is bordered by a row of chestnut trees.
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.
