St.Peter's congregation of Tartu was established on 27 October 1869 and the St. Peter's Church was consecrated in 1884. This pseudogothic imposing building was built pursuant to a design by E. Schröder. The location was symbolic of the time of the Estonian awakening: in the proximity of the square where the first general Estonian song festival took place. The church was finally completed in 1903, when the freshly finished 55- metre chief tower and four corner towers were consecrated. A 22- register organ and the altar painting, "Dying Christ" (by J. Köler), were finished in the 1890's. Both church bells have been cast in Gatsina near St. Petersburg.

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.
