Harlech Castle (Harlech) - This another of King Edward I's 13th century English castles, built to stamp out any more revolts by the Welsh. Situated on the sea, Harlech Castle still gives the impression of a mighty fortress. The turreted gatehouses and ramparts are a delight to explore.
Just outside of Harlech, Llanfair Quarry produced million of roof slates, called a "Welsh Lady." Today, tour the nine caverns of the Llanfair Quarry Slate Caverns, to see where slate was mined, and steps cut into the stones, called Jacob's Ladder.
