Walk around the town of Rhuddlan in North wales,

too late in the evening for a castle tour. maybe next time
The town is known for the ruins of Rhuddlan Castle, built by order of King Edward I from 1277 to 1282, and for the site of another castle at Twthill, built by the Norman Robert of Rhuddlan about 1072. Well-preserved Rhuddlan castle has a great round tower and many surviving walls.
