House of Perkūnas is one of the most original and archaic Gothic secular buildings, located in the Old Town of Kaunas, Lithuania. Originally built by Hanseatic merchants and served as their office from 1440 till 1532, it was sold in the 16th century to the Jesuits who had established a chapel there in 1643. The Jesuits have also completed the Church of St. Francis Xavier at the Town Hall Square in 1722.
The ruined house was rebuilt in the 19th century and served as a school and theatre, which was attended by Polish-Lithuanian poet Adam Mickiewicz. At the end of the 19th Century it was renamed 'House of Perkūnas', when a figure, interpreted by the romantic historians of that time as an idol of the Baltic pagan god of thunder and the sky Perkūnas was found in one of its walls. Today, the house of Perkūnas once again belongs to the Jesuits and houses a museum of Adam Mickiewicz.
Lithuanian historian, theologian and translator Albert Wijuk Kojałowicz was born in the house.
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.
