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.

From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
