The Roosna-Alliku Manor was donated to von Rosen family in 1620 by Christina, Queen of Sweden. The coat of arms of family features a white rose, which has become the symbol of the manor. In 1721 it was acquired by von Stackelbergs. The present main building is one of the most impressive examples of early classical manor architecture in Estonia, completed by Otto Friedrich von Stackelberg in 1786. Worthiest of attention in the interior are the two rooms with artificial marble walls. The manor building has been a school since 1924. Visits during the school period are possible by appointment only.

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.
