There has been a manor house on the site of Keila-Joa manor (Schloss Fall) since the 17th century. The present manor house was built in 1831-1833 and designed by St. Petersburg architect Andrei Stackenschneider. The manor represents one of the earliest examples of neo-Gothic architecture in Estonia. It was built for the family of count Alexander von Benckendorff (whose graves can be found in the park adjacent to the manor) and the building saw many prominent guests during the Imperial years, among others the Russian royal family, famous soprano Henriette Sontag and composer Alexei Lvov.
From 1927 to 1940 it was used by the Estonian Ministry of Foreign Affairs. During the Soviet occupation it was used by the Red Army. The centre of the manor now belongs to the Estonian Ministry of Foreign Affairs, but is not being used currently and is awaiting restoration. In 2010 the manor was sold into private hands.
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.
