Originally the home of the Vaughan family, Tretower gives you two historic buildings for the price of one: the sturdy circular Norman keep, now roofless and commanding only a sheep-nibbled bailey, and a 15th-century manor house with a fine garden and orchard (now furnished with picnic tables). Together they illustrate the transition from military stronghold to country house that took place in late-medieval times. It's 3 miles northwest of Crickhowell on the A479. Prebook tickets online.
