Harlech Castle in Gwynedd, Wales, is a Grade I listed medieval fortification built onto a rocky knoll close to the Irish Sea. It was built by Edward I during his invasion of Wales between 1282 and 1289. Over the next few centuries, the castle played an important part in several wars, withstanding the siege of Madog ap Llywelyn between 1294 and 1295, but falling to Prince Owain Glyndŵr in 1404. It then became Glyndŵr's residence and military headquarters for the remainder of the uprising until being recaptured by English forces in 1409.
During the 15th century Wars of the Roses, Harlech was held by the Lancastrians for seven years, before Yorkist troops forced its surrender in 1468, a siege memorialised in the song 'Men of Harlech'. Following the outbreak of the English Civil War in 1642, the castle was held by forces loyal to Charles I, holding out until 1647 when it became the last fortification to surrender to the Parliamentary armies. In the 21st century the ruined castle is managed by Cadw, the Welsh Government's historic environment service, as a tourist attraction.
UNESCO considers Harlech, with three others at Beaumaris, Conwy, Caernarfon, to be one of 'the finest examples of late 13th century and early 14th century military architecture in Europe', and it is classed as a World Heritage Site. The fortification is built of local stone and concentric in design, featuring a massive gatehouse that probably once provided high-status accommodation for the castle constable and visiting dignitaries. The sea originally came much closer to Harlech than in modern times, and a water-gate and a long flight of steps leads down from the castle to the former shore, which allowed the castle to be resupplied by sea during sieges. In keeping with Edward's other castles in the north of Wales, the architecture of Harlech has close links to that found in the County of Savoy during the same period, an influence probably derived from the Savoy origins of the main architect, James of Saint George.
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.
