Bleijenbeek Castle was built of bricks around 1300. According to the 19th-century historian A.J. van der Aa, the castle is known for its numerous sieges by the armies of Guelders and Spain. In 1580, the castle was besieged by the forces of Guelders, but it was defended bravely by the lord of the castle, Marten Schenk. When the Duke of Parma sent cavalry, the besieging army had to retreat. In 1589, Schenk changed sides, and the castle was besieged by Marcus van Rije, the stadtholder of Guelders appointed by the Spanish king; this time, the castle was conquered.
The castle has lain in ruins since the bombardment by the British RAF on 21 and 22 February 1945, during Operation Veritable. In 2009, the property was purchased by the Bleijenbeek Foundation, which intends to restore the remaining structure, moat, and surrounding gardens and provide public access after work is complete. Construction began in the summer of 2012.
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.
