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 of Bromfield and Yale 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.
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).
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.
The only sizeable part of Holt Castle that remains is perched on its sandstone base. Some masonry features are still visible, including the lower walls of the inner keep, the postern gate, a buttress, a chute exit and the foundations of the outer gate's square tower.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
