John Knox House Museum, Edinburgh

It's not certain that John Knox, the 16th century Reformation leader, actually died here - but he might have, so there's a museum inside this 15th century house dedicated to all things Reformatory. Find out all about John Knox's concerns about Catholicism and his inimitable way of dealing with such qualms. The subject matter is such that the museum can get quite heavy-going, but even a little persistence is richly rewarded by insights into this area of Scottish history. Particularly interesting is an audio re-enactment of Knox's debate with the Catholic Mary, Queen of Scots.
