The estate was first mentioned in 1466. It has been associated with the Gilsens, von Rosens, von Zoeges, von Benckendorffs, von Krusensterns and von Uexküll-Güldenbandts. The ruins of a vassal castle destroyed during the Livonian War were reconstructed as a stately castle in the 17th to 18th centuries, which received its present form in 1790.
For many years, the manor was the home of a world famous explorer and mariner Adam Johann von Krusentern, who also passed away in Kiltsi. Since the 1920s, the manor houses a school. The building has been thoroughly restored starting in 2000.
the mansion can be rented for celebrating birthdays and weddings, organizing trainings and seminars, and in summer you have the opportunity to visit the mansion.
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.
