Rudbaxton Rath is a ring-shaped enclosure together with a ringed keep in the parish of Rudbaxton. It is the remains of a medieval defensive ringfort, hillfort or castle, probably made of timber. At the site are the remains of light earthwork. The nearly circular interior area is surrounded by a counterscarp and measures around 100 metres north to south by 95 metres east to west. A possible entrance has been identified at the north side. There is a rampart that is around 3 metres high. Within the western rampart an elliptical enclosure can be seen, measuring (north-northwest to south-southeast) roughly 50 metres by 32 metres.
Artefacts at the site include unspecified armour and two rings made of iron approximately 20 cm across. Two twisted iron rings were discovered about 20 cm in diameter. It is possible that they were once torcs. Also found at the site is a half-scale model of a human hand, also made of iron. This hand may be Roman or Iron Age.
Exterior to the enclosure at the east are the remains of a chapel.
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.
