Arenfels Castle dates originally from the 13th century and was converted as Renaissance palace in the late 16th century. The castle got its current neo-Gothic appearance in 1849-1858. During the battles for Remagen Bridge in the Second World War, the building fabric was considerably damaged. Most of the war damage has been repaired today. The beautiful interiors of the castle have been restored, and the imposing cast-iron staircase from the Sayner ironworks is particularly worth seeing.Arenfels Castle, with its location in the middle of the vineyards, is a romantic venue for weddings, family celebrations and corporate events.
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.
