Long before the road bridge, Rhuddlan Castle was restocked by boats from the sea
Rhuddlan's castle was built by English king Edward I in the mid 1200s at the same time as Flint Castle and as part of his plan to rule Wales.
Experts say it was planned as a concentric castle with a unique diamond layout as the gatehouses are positioned at the corners of the square baileys instead of along the sides like at Flint.
Welsh monument group CADW, which maintains the castles, says two important political events are linked with Rhuddlan.
In 1284, the Statute of Rhuddlan officially brought Wales under English rule; and while in Rhuddlan, Edward I announced that he would make his son, born at Caernarfon Castle, prince of Wales.
rebelled in 1400, his troops attacking the town but they did not capture the castle.
In the Civil War, the castle was for King Charles, but when he lost power, the Sherriff of Flintshire was told to make it unusable. Since 1648 the castle has been in ruins.
