Hawarden Old Castle origins are indeterminate and the oldest fortifications on this site may date back to the Iron Age, later being used as a Norman Motte-and-bailey castle which was reportedly destroyed and replaced in a short period during the 13th century.
The castle played an important role during the Welsh struggle for independence in the 13th century. At Easter 1282, Dafydd ap Gruffudd attacked Hawarden Castle, thereby starting the final Welsh conflict with Norman England, in the course of which Welsh independence was lost. King Edward I's sense of outrage was such that he designed a punishment for Dafydd harsher than any previous form of capital punishment; Dafydd was hanged, drawn, and quartered in Shrewsbury in October 1283.
In 1294 the castle was captured during the revolt of Madog ap Llywelyn.
After the English Civil War in the 17th century the castle was slighted on the orders of Oliver Cromwell. Its ruins are on the New Hawarden Castle estate and are open to the public on some Sundays, typically the second and fourth Sundays in summertime.
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.
