Holt Castle was a medieval castle in the town of Holt, Wrexham Borough, Wales. Work began in the 13th century during the Welsh Wars, the castle was sited on the Welsh-English border by the banks of the River Dee.
In the medieval period, the five-towered fortress was actually known as Castrum Leonis or Castle Lyons because it had a Lion motif carved into the stonework above its main gate. In the 17th century, almost all the stonework was removed from the site; only the base of the sandstone foundation remain.
Holt castle was started by Edward I on a sandstone base next to the River Dee soon after the invasion of North Wales in 1277. In 1282 Edward I presented the Welsh lands in which Holt was situated to loyal lord John de Warrene, who was also given the task of completing the castle. By 1311 the castle had been finished and a planned town laid out next to it for the use by English settlers.
A century later, Welsh forces burned down the town in 1400 during the uprising of Owain Glyndŵr; although the castle was not taken.
For most of the First English Civil War, Holt was garrisoned by Royalists troops. It was captured by the Parliamentarians in 1643 but retaken by the Royalists in spring of 1644. After they had surrendered, thirteen of the Parliamentarian garrison were put to the sword and their bodies were thrown into the moat. In January 1647, after a siege that lasted for nine months the Royalist governor, Sir Richard Lloyd surrendered Holt to the Thomas Mytton (the commander of the besieging Parliamentarians)—after Holt's surrender Harlech was the only stronghold in Wales still under Royalist control and it fell to Mytton in March of that year. After the surrender Colonel Roger Pope was appointed Parliamentary governor of the Holt. By order of Parliament Holt was slighted later that year.
Between 1675 and 1683 much of the castle was taken away by Sir Thomas Grosvenor, 3rd Baronet of Eaton, who used barges to carry the stonework downstream to rebuild Eaton hall after the English Civil War.
In the 18th century all that remained of Holt Castle was part of a tower and a rectangular building.
Today the only sizeable part of Holt Castle that remains is the sandstone base. However a few masonry features are still visible, like the postern gate, a buttress and the foundations of a square tower.
