The Bookshop, Wigtown, Scotland. The biggest second-hand store in Scotland has a mile of shelving & >100,000 books. It also has a lovely story: “Jessica Fox worked for NASA in LA, loved books & had always wanted to visit Scotland. She Googled ‘Secondhand bookshop, Scotland’- this was the first to pop up. She ended up working there”. Yet another reason to go to majestic Scotland.
