Holt Castle  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 remains. The castle, which was constructed between 1277 and 1311, was built from local sandstone on top of a high promontory. It was shaped like a pentagon with towers at each corner. The castle had a stepped ramp up to a main gateway, barbican, inner ward, postern and curtain walls. There was also a water-filled moat that was fed from the River Dee. The design of the castle featured towers that were built against the face of the rock outside the curtain wall, similar to the inner wards at Ruthin and at Conwy. 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 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 of 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. By the 16th century Holt Castle had fallen into disuse and ruin. The English Elizabethan map maker John Norden surveyed the castle and noted that it was "nowe in great decay". 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 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.
