In 1622, Vihterpalu estate was granted to Thomas von Ramm by the Swedish king Gustavus Adolphus. The present building probably dates from the 19th century and is in a late Neoclassical style. Elisabeth von Ramm married Gustav von Knorrig in 1816 and they started to build a new main building, which was completed in the 1820s. The façade is dominated by a central pedimented section.
Today Vihterpalu manor provides accomodation, event and conference services.
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.
