Conwy Castle — my personal favorite — is dramatically sited on a rock overlooking the sea, with eight mighty drum towers. It was a power statement from the English king to the Welsh — who had little more than bows and arrows to fight with.
The castle is built on solid rock, making it impossible for Welsh malcontents to tunnel underneath the walls. The English paid dearly for Conwy’s construction through heavy taxes. And today, with the Welsh flag proudly flying from its top, the English happily pay again just to visit.
Because British castles often protected key roads and rivers, many of them match up with the main sightseer circuit. More than a few are jazzed up with battle reenactments, sound-and-light shows, catapult demos, dress-up costumes, and medieval banquets.
But beyond the touristy venues are the castles I prefer — the forgotten ones. Medieval fortresses are rotting away throughout Britain, their stones picked over and carted away to build other things.
In Scotland, St. Andrews Castle is an evocative empty shell that invites you to fill-in-the-moat, and the ruins at Urquhart Castle, on the Loch Ness, are gloriously situated with a view of virtually the entire lake.
The grassy hilltop at the textbook motte-and-bailey Norman ruins at Pickering, in the North York Moors, is perfect for understanding the fort’s strategic location.
These landmarks from times past tell their stories all over Great Britain. Make time for both castle types — some forgotten, some discovered — in your itinerary. You'll find castle thrills lurking in every direction.
