The Church of St. Tysilio and St. Mary stands on a site that was once the centre of early Welsh Christianity. The church has been rebuilt and modified throughout the centuries, and there are examples of work surviving from every architectural period from the Normans to the present day.
The site is believed to have become a Christian foundation c.550, dedicated first to St. Gwyddfarch, and later to St. Tysilio. The remains of this early church were still visible in the eighteenth century, but little trace remains today. A second church was built in the twelfth century by Madoc Mareddud, whose remains are believed to be buried within the grounds; much of the fabric of this building remains today.
Since the first foundation of the church it been extended and renovated on a number of occasions, and has an eclectic range of styles; a wide Romanesque nave, fourteenth century moulded entrance, fifteenth century tower and south window, seventeenth century octagonal font, and predominantly nineteenth century fenestration and fixtures, such as the oak pulpit. The pews were made in the nineteenth century but incorporate seventeenth century panel screens.Built from predominantly local rubble stonework with a slate roof and dressings that include stone gargoyles, this church is a display of Welsh Christianity through the centuries.
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.
