Cardigan Castle holds an important place in Welsh culture, having been the venue for the first competitive National Eisteddfod, held in 1176 under the aegis of Lord Rhys ap Gruffydd. Neglected for years, it's sprung from the ashes via a multimillion-pound refurbishment and now stands as a major centre of local Welsh culture, with live performances, language classes, eisteddfods and more taking place within its hollowed-out walls.

There's a restaurant, kitchen garden and accommodation (making use of old stables and other extant structures; doubles start at £90 or it's £420 per week for self-catering). You can even see the most northerly colony of greater horseshoe bats squatting in the medieval cellar beneath the handsome Georgian house that now dominates the grounds.
