St. Michael Archangel church is the oldest building in Gdynia. Originally built by nuns of the Norbertine Order, it replaced a pagan temple in 1224. The church was reduced to a pile of rubble during the war with Sweden in 17th century. After its restoration it served the Catholics until the last days of World War II when the tower was hit by a Soviet cannon ball, fired for fun. Yet again did the Kashubians have to rebuild their temple. It towers the Kępa Oksywska up to over 40 m above the water table, surrounded by a cemetery. Very many honourable people from Gdynia and Pomerania rest there; it also makes a Pantheon of the Navy: the walls of this historic church are lined with commemorating plates honouring the II World War Polish warships, graves of the outstanding navy commanders and the September 1939 defenders of the Polish Coast, holders of the Virtuti Militari crosses.
References: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.
