Traquair is said to be Britain’s oldest inhabited house. It existed in 1107 and has been extended since then. The lower side wings were remodelled in 1695-1699. The house was used by various Scottish kings and has a long association with Jacobites and Catholicism. Mary Queen of Scots stayed here and one can see her bed and the cradle in which she rocked the infant James.
A number of rooms on several floors are opened to visitors, containing period furniture, artifacts and facsimile documents. The High Drawing Room has recently rediscovered painted beams exposed in the ceiling. On an upper floor there is a large priest’s room with a concealed spiral staircase leading down. There is a lot to look at inside the house.
The Dining Room and Lower Drawing Room are in one of the wings, built 1694. In the other wing are the post-Catholic emancipation chapel, the brewhouse, exhibitions and the shop. In the grounds are a walled garden, woodland walks, a menagerie, a maze and a pond, formerly a loop of the Tweed river.
I did not have time to explore the grounds.
There is a lot to see here, so you should schedule a longer visit.
