Rambling through the ruins of Europe's castles

Rambling through the ruins of Europe's castles - Travel - Destination Travel - Europe - msnbc.com: "But beyond the touristy castles are the ones I prefer — the forgotten ones. These are evocative, stony husks without plaster or furnishings — where you'll see broken stairways and open skies rather than rooftops. Massive chunks of stone no longer guard anything from anyone and lichen grows on walls seemingly to cushion stones for a fall they've been expecting for centuries. Castle ruins invite you to ramble the ramparts and let your imagination roam. Climbing through waist-high weeds on rubble corralled by surviving walls, you can break off a spiky frond and live a sword-fern fantasy."
