A 17th century townhouse right next door to Stirling Castle. Like the castle itself, some of the restoration efforts actually undermine the experience by replacing one's imagination of what may have been with a mediocre reproduction.
If you're going to Stirling Castle, it's worth taking a 15 minute walkthrough (as others have stated, admission is included with the castle). That said, if you're short on time, I'd prioritized the graveyard at the Church of the Holy Rude instead (across the street).
