Located in the grounds of Hay Castle, Wales is the Honesty Bookshop, a 24-hour open air bookshop where people select books and post the money for them through a small letterbox. Hardbacks at 50p and paperbacks at 30p. The Castle is at Hay-on-Wye, the “town of books,” so much so that according to my guidebook “if you don’t like books, you should certainly avoid Hay-on-Wye.” If you’re of the sort who does, however, be sure to make it out for the Hay Festival of Literature and Arts.
