Arévalo castle was built in the 14th century and reformed during the 15th and 16th centuries. It has a pentagonal ground plan and a large Tower of Homage. Inside there is a Cereal Museum.
King Pedro I, the Cruel, locked his wife Blanca de Borbón in the castle. Juan II and Enrique IV possessed it, the latter handed it to don Álvaro de Zúñiga; between 1476 and 1480, Zúñiga and the Catholic Monarchs negotiated a compesation for Arévalo and, in the ends, the village was taken over by the Crown. Subsequently it became a state prison.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.
