Hobøl Church is considered to be one of Norway's best preserved medieval churches. The church was built in granite in Romanesque style at the end of the 12th century (around 1175). The baptismal font with granite basin and steatite base dates from medieval times and is probably as old as the church itself. The altarpiece dates from c. 1600 and pulpit was a gift from Adrian Busch in 1602 and is made by Nicolaus Petri Ripen.
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.
