I have for you this evening a small puzzle. In the photograph I took today you see some feet and a large X in the road. The feet are mine and the X marks a significant event in history. The puzzle is to tell me what the event was.

I can tell you that the X is not the site of buried treasure. It is not part of a giant noughts and crosses game. And it isn’t where my cat was run over.

All will be revealed later this week in a post where I will include the best responses.
