Kokemäki Castle (Kokemäen linna) was a medieval castle in Kokemäki town. The time of its foundation is unclear, but the castle was most likely completed in 1324-1325. It was demolished in 1367 by order of King Albert, as the local residents complained of heavy taxation for the upkeep of the castle. The castle was located on the Linnaluoto Island in the river Kokemäenjoki.
Kokemäki Castle was the administrative centre of Kokemäenkartano slottslän. Its function was similar to that of the castles of Turku, Häme and Vyborg, which are still preserved today. The only known reference to Kokemäki Castle is King Albert's warrant for the demolition and relocation of the castle, dated 12 July 1367. It was probably built of limestone and equipped with a round tower. In 1364–1365 Kokemäki Castle was besieged by the army of King Albert as the castle was under the rule of Magnus IV of Sweden.
Archaeological excavations were made in 1885. Various items were found which were dated to the late Bronze Age, as well as to the 13th and 14th century. After the demolition of Kokemäki Castle a new castle, Aborch, was established. Location of this castle is uncertain, since it was disbanded in the 1410s. It was probably built 1.5 kilometres upstream at the same location as the later Kokemäenkartano manor.
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.
