The Caerleon Roman Fortress and Baths museum is a historical site located in the town of Caerleon. Roman Wales was the farthest point west that the Roman Empire in Roman Britain extended to, and as a defence point, the fortress at Caerleon built in AD 75 was one of only three permanent Roman Legionary fortresses in Roman Britain. It was occupied and operational for just over 200 years.
The site of the baths was excavated in the late 1970s, and a curator was appointed in 1980 when the site was opened to the public.
The Roman Baths Museum lies inside what remains of the fortress of Isca Augusta close to the National Roman Legion Museum. The baths museum has a covered walkway over part of the remains of the military bath house. There was a frigidarium, tepidarium and caldarium, as well as an open-air swimming pool.
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.
