A wealth of legend, poetry, and song is conjured up by the 13th-century Harlech Castle, built by Edward I to help subdue the Welsh. Its mighty ruins, visible for miles, are as dramatic as its history (though you have to imagine the sea, which used to crash against the rocks below but receded in the 19th century). Harlech was occupied by the Welsh Prince Owain Glyndwr from 1404 to 1408 during his revolt against the English. The music of the traditional folk song "Men of Harlech" refers to the heroic defense of this castle in 1468 by Dafydd ap Eynion, who, summoned to surrender, is alleged to have replied: "I held a castle in France until every old woman in Wales heard of it, and I will hold a castle in Wales until every old woman in France hears of it." On a clear day you can climb the battlements for a spectacular view of the surrounding countryside. The castle dominates the coastal town of Harlech, 12 miles south of Porthmadog.
