Alberweiler Castle is a small castle-like structure where the ground and the first floor of the castle are made of stone and the upper storeys consist of three projecting half-timbered floors.
A castle is first mentioned in sources dating from the 11th century. It was occupied by knights in the service of the Counts of Berg-Wartstein. This early structure was destroyed in 1487 but soon after, towards the end of the 15th century, a new castle was erected at the behest of Bartholome of Warthausen. Some remains of the circular rampart are still visible. Following the extinction of the house of Warthausen zu Alberweiler in 1585, the castle was enfeoffed to the Counts of Stadion by Emperor Rudolf II. The castle was renovated in early-Baroque style in the 17th century. The gate was also constructed during these restoration works. At around 1700, the castle functioned as residence for the local reeve, the Counts of Stadion residing at Warthausen Castle, and subsequently went into private ownership during the course of the 18th century. In 1826, the Counts of Stadion sold all rights to the village and the castle to the Kingdom of Württemberg. Following alterations in 1880 the structure slowly began to fall into disrepair. The castle was extensively restored in the late 20th century and is privately owned today.
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.
