Lappee church is a wooden so called double cruciform church situated in the centre of the city. The church was built in 1794 by Juhana Salonen, a church builder from Savitaipale. During the years the building has gone through many renovation and modification works.
Aleksandra Frosterus-Såltin has painted the altarpiece, which represents the Ascension of the Christ, in 1887. The other paintings are made by unknown artists. The existing organs are from the year 1967. The church serves travellers as a road church.
South of the church stretches the graveyard, with an evocative war memorial, which features cubist and modernist sculptures commemorating Finns who died in the Winter and Continuation Wars. The most striking depicts a mother mourning her soldier son lost in battle, by Kauko Räsänen.
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.
