Caer Gybi Roman Fort, Holyhead, United Kingdom

Caer Gybi in Holyhead contains the remains of a small Roman fortlet and naval base, whose atmospheric ruins can today be explored. Although the construction date of Caer Gybi is unknown, it is believed that it was built in the late 3rd or early 4th century. The structure was made up of three defensive walls with circular watch towers at each corner, while the fourth side fronted the sea and may have been a dock for the Roman warships that would have patrolled the area.

It is thought that Caer Gybi was constructed to defend against Irish sea raiders, and as a smaller fortlet was probably an outpost of the larger Roman fort at Segontium. It is believed that the Roman watchtower, which stood on the nearby Holyhead Mountain, served as the lookout post for Caer Gybi.

The Romans abandoned the region in the late 4th century, and by the 6th century the site had been given to Saint Cybi who founded a monastery within the walls. The medieval Church of St Cybi still stands there today.

Today, visitors to Caer Gybi can still view much of the original Roman defences, with walls standing up to 4m in places and at least one original corner tower.

Caer Gybi Roman Fortlet is a small fortification on Anglesey’s Holy Island, in North-West Wales. It is one of Europe’s only three-walled Roman forts, the fourth side facing the sea and most likely used as a quay. The walls of this fort are surprisingly well preserved, standing 4m tall and 1.5 thick. There are remains of towers on each corner. The most prominent tower is on the North East corner but this is thought to have been rebuilt in the medieval period. The Romans left Caer Gybi in 393. In the 6th century the fort was given to St Cybi who built a monastery there. The site is free to enter and reasonably interesting if you know what to look for.

Church of St Donatus

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.
