Simuna church is one of the oldest in Estonia although its exact building time is unknown. It has been destroyed in wars and rebuilt again several times during centuries, at least in 1728-29 and also 1885-86. From the old church has remained part of a tower that was used on protective purposes. The altar was made by C. Ackermann, a famous wood carver and the altarpiece was made by Carl Sigismund Walther. The organ was built by Gustav Normann and so it is one of the oldest organs made by an Estonian. Visitors can visit a platform on the top of the bell-tower and enjoy a marvelous view on surroundings. The tower is 53,5 m high.
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.
