Saint Padarn's Church is one of the largest medieval churches in mid-Wales. Founded in the early sixth century it has gone through many changes, from a Welsh monastic centre, a Benedictine priory, a royal rectory, a church controlled by Chester's Vale Royal Abbey, and since 1538 a parish church under a vicar.
St Padarns is a fine, large thirteenth century church, featuring an aisless nave with transepts and central tower. It was extended around 1475 and was substantially restored in stages from 1867 to 1884 by John Pollard Seddon. Two medieval crosses are preserved within the church.
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.
