Mörby was first mentioned 1387 as built by the knight Henrik Damerow. Since 1452 it was owned by Oxenstierna family over 250 years. 1550 the castle was rebuilt after a fire. In 1733 it was left as a decay and the roof was ripped off and moved to Ekeby Castle. Finally Mörby was destroyed by fire in 1740. Today still impressive ruins remain including a tower body.
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.
