The Pommern, formerly the Mneme (1903–1908), is a four-masted barque that was built in 1903 in Glasgow at J. Reid & Co shipyard. It was one of the Flying P-Liners, the famous sailing ships of the German shipping company F. Laeisz. Later she was acquired Gustaf Erikson of the Finnish Åland archipelago, who used the ship to carry grain from the Spencer Gulf area in Australia to harbours in England or Ireland until the start of World War II. After World War Two, she was donated to the town of Mariehamn as a museum ship.
Today Pommern is part of the Åland Maritime Museum representing the history of ship and seafaring in Åland. The Maritime Museum is considered as one of the world’s finest museums related to merchant sailing ships.
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.
