Jedburgh Castle Jail & Museum

This castle, which was used as a prison in the 19th century, is the second most important attraction in the town of Jedburgh. In perfect condition, it's most famous because it's supposedly being haunted by a notable prisoner for the last two centuries. Inside, you can read curious stories from prisoners of the time of how sentences were applied for up to 30 days for stealing a potato, or that prisoners were separated into galleries depending on the crimes. Given that admission is free, I think it's worth giving a few coins that are often begged for. A very peculiar place.
