"Dundas Castle is the real deal: a 15th-century castle about 40 minutes west of Edinburgh that can only be rented in its entirety. There are 17 bedrooms, so you can be the Laird of your own castle for as long as you (can afford to) stay there. The oldest part dates back to 1416, with the grand, now-main building dating from 1818. Some of Scotland’s most glamorous weddings take place here." - Freya Herring
