Jõelähtme church is one of the oldest churches in Harjumaa County. The building of Gothic-styled church was started in 1220s and completed in the beginning of 14th century. Jõelähtme church was consecrated to Virgin Mary.
The church has been rebuilt several times. The last rebuilding in 1910 was carried out after a conflagration: the gable end tower was replaced by a massive tower erected in front of the portal. Although the church has been subject to damage at various times, it still has the Late Renaissance pulpit and the Baroque altar (completed in 1670).
The grave of Gustav Heinrich Schüdlöffel (1798-1859), pastor who ministered the congregation for a long time and is known for his literary achievments, can still be seen in the cemetery. In March 2000 the altar crucifix, two candlesticks, four chandeliers, two girandoles and the contribution box were stolen from Jõelähtme church. In April 2001 the thieves returned the stolen objects.
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.
