This pleasant little town on the river Clwyd is about 3 miles S. of Rhyl. It is worthy of a visit for its famous old ruined castle. Like most of the native Welsh castles, it has a very chequered history, dating back to Preconquest days. It changed hands from Welsh to Norman, then to Welsh again, and was finally captured and rebuilt by Edward I in 1277. Rhuddlan, indeed, was an important place in those days, for it was right on the course taken by the invading English armies. Indeed, it was usually, in modern terms, the end of the first phase of invasion. Beyond it, the real fighting began. It was in Rhuddlan Castle, too, that the Prince was born whom Edward, by guile, managed to foist on the Welsh as Prince of Wales. Today the castle looks gentle and brooding, with its round towers looking down on the narrow waters of the Clwyd. Rhuddlan also boasts an old Parliament House and an old Banqueting House.
