Cilgerran Castle (Welsh: Castell Cilgerran) is a 13th-century ruined castle located in Cilgerran, near Cardigan. The first castle on the site was thought to have been built by Gerald of Windsor around 1110–1115, and it changed hands several times over the following century between English and Welsh forces. In the hands of William Marshal, 2nd Earl of Pembroke, the construction of the stone castle began after 1223.
After passing through successive families, it was left to ruin and eventually abandoned by 1400. The castle backs onto a cliff face, with the remaining ruins dating from the 13th century. It was most heavily fortified where it faces inland, and includes a pair of drum towers, rather than a central keep, which remain standing. It passed into the hands of the National Trust in 1938, who open it to the public.
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.
