The church in Vallensbæk Village dates back to the 1100s, built in the years 1150-1200. It is a typical village church, which originally consisted of cows and ships in Romanesque style built in chalk quarters. The tower has only come to later, in the 16th century, and is listed in the bedoque style. The church of Vallensbæk came to the Reformation in the King's possession, but in 1688, the Office of Ethics and Counselor Caspar Schiøler acquired the church. Later in 1755, he passed over to the owner of the estate, Hans Nicolai Nissen, and after his death, under the Nissen Foundation. Until the fire in 2007, you could still see the signature and monograms of NH Nissen and after his nephew, W. Pechüle, you in Vallensbæk 1801-45, on the altar's roof. The church was privately owned until the mid-1950s. Today the church is owned by the church at the church council.
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.
