Meistersel Castle is a ruined castle near Ramberg on the outskirts of the Palatinate Forest. It is located on a 492-metre-high hilltop that towers above the Modenbach valley near the Three Beeches pass (Drei Buchen) on the road from Ramberg to Edenkoben.
Meistersel Castle is one of the oldest castles in the Palatinate. It was built in the 11th century and mentioned first time in 1100 and it was probably built to protect Trifels imperial castle. In the 12th century, the Meistersel was given as a fief to knightly servants. The core of today's complex was built around 1300 after fundamental renovation work. During the Peasants' War in 1525 the castle was looted by rebels and subsequently abandoned.
Its name is derived from the words Meister ('master') and Saal ('hall') and hence the term Meister des Saales or master of the hall/chamberlain. It is likely that it was a seat for ministeriales of the imperial castle of Trifels. Its other name, Modeneck, comes from the name of the nearby stream.
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.
