The first church in Haukipudas was probably built in the Middle Ages and it was located to the Kello village. The church or chapel was mentioned in the letter dated back to the year 1488 (found from the Vatican archives of Pope Innocent VIII).
The present wooden cruciform church was completed in 1764. It is designed by Matti Honka and built by Jaakko Suonperä. Originally Haukipudas church was named as Ulrika’s Church. Interior of the church is very richly decorated by paintings of Mikael Toppelius (1774-1779).
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.
