Best Nature and Parks (RV, National, Dog, etc) in Hay on Wye

The building was subsequently remodelled in a succession of medieval architectural styles.The signature highlight is the magnificent Mappa Mundi, a single piece of calfskin vellum intricately painted with some rather fantastical assumptions about the layout of the globe in around 1290. The same wing contains the world's largest surviving chained library of rare manuscripts manacled to the shelves."
