Großbüllesheim Castle was first mentioned in records in 1402, in the fiefdom of the Duke of Jülich, enfeoffed to Reymer Spies von Büllesheim, whose descendants still flourish today as the Barons Spies von Büllesheim. Büllesheim castle was originally built in two parts next to a weir, as a knight's country seat. Of this only the gate-tower of the residential house remains, built onto the fore-castle. The fore-castle itself has undergone no major changes in 350 years, apart from minor renovation work. The buildings of the main castle preserved till today date back to the 17th century and underwent major transformations in the 19th century, so that now Büllesheim castle is no longer recognizable as the main castle. The moat is no longer visible, either, as it dried out and was filled in with sand and earth.
The castle was in the fiefdom of the Duke of Jülich until 1802, when the last Duke of Jülich, Ludwig von Brempt, died. From then on, it was no longer the country seat and rapidly fell into disrepair. Today only the three-winged fore-castle has been preserved. In 1867 the estate was bought by the Nettekoven family, who divided the land and farm and constructed a second residential house in 1886, so that now there are two distinct farms, separated by a wall.
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.
