Ruthin Castle is a medieval castle fortification in Wales, near the town of Ruthin in the Vale of Clwyd. It was constructed during the late 13th century by Dafydd ap Gruffydd, the brother of Prince Llywelyn ap Gruffudd, on a red sandstone ridge overlooking the valley. Part of the ancient walls still remain and now form part of the Ruthin Castle Hotel.
Ruthin Castle occupies a site that was first used as an Iron Age fort. In 1277, Edward I of England granted the land to Dafydd ap Gruffydd in gratitude for his assistance during the invasion of North Wales. It is unclear whether there was an existing fort on the site or whether Dafydd established the castle.
Between 1579 and 1580, the Castle was used for the imprisonment and torture of Welsh poet, recusant schoolmaster Richard Gwyn, who was hanged, drawn, and quartered at Wrexham in 1584. Gwyn was canonized in 1970 by Pope Paul VI as one of the Forty Martyrs of England and Wales.
At the start of the English Civil War the castle was in a state of disrepair and the necessary works were hastily performed to make it defensible. It withstood an eleven-week siege by parliamentary troops in 1646 before surrendering when the attackers announced that they intended to lay mines under the walls. Oliver Cromwell's forces later dismantled and demolished the castle, in a process of organised de-fortification called slighting.
In 1923 the castle became Britain's first private hospital for the investigation and treatment of obscure internal diseases, but this was closed in about 1950. Since the 1960s the castle remains have been incorporated into a hotel.
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.
