Ēdole Castle was built for the bishop of Piltene between 1264 and 1267. It was rebuilt in the 16th century and from 1561 until 1920 it was the property of the Baltic-German Baron von Behr and his descendents.
During the 18th century the castle was expanded and from 1835 to 1841 it underwent a major reconstruction work to become one of the first samples of Neo-Gothic architecture in Kurzeme. The building was partly burned during the Russian Revolution of 1905. Between 1906 and 1907 a household yard and tower were built in one of its corners, being the façade remodelled with its Gothic forms preserved.
Originally consisting of two residential buildings linked by a stone wall, the castle is surrounded by landscape park. It is considered an architectural and archaeological monument of national importance.
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.
