Traquair House
Said to be the oldest continually occupied home in Scotland (since 1107), Traquair House has secret stairways and passages, a library with more than 3,000 books, and a bed said to have been used by Mary, Queen of Scots in 1566. You can walk freely through the rooms, and each has an explanatory leaflet as well as helpful guides dressed in period costumes. The top floor of the house is an interesting small museum. Outside is a reasonably scary maze, an adventure playground, and some lovely woodland walks as well as pigs, goats, and chickens. The 18th-century brewhouse still makes highly recommended ale, and there's a café on the grounds near the beautiful walled garden. The Traquair Fair in August is the closest you are likely to get to a medieval fair around these parts, and well worth the visit. You may even spend the night if you wish.
