The Church of St. Lawrence in Mynämäki is the second biggest medieval church in Finland. The sacristy, oldest part of the church, is dated back to the 13th century. The church itself was quite probably erected in the beginning of 15th century to replace the previous wooden church. It was expanded in 1600s and again in 1770s.
There are couple of old artefacts inside the church, for example wooden epitah from year 1624 and memorial of Fleming noble family also from the 1630s. Finnish National Board of Antiquities has named the church site as national built heritage.
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.
