Just to get you in the right mood for my weekend teaser... ![]()
Here's a picture of a cannon...

Now this isn't any old cannon... oh no, it's a very special cannon with a very special history.
The cannon is currently situated in a castle described by yours truly as the Jewel in Monmouthshire's Crown...
Find the location f the castle and you should be able to find some information about the cannon. 
Now, what I want to know is...
1. Where did the cannon come from?
2. How did it end up in its present location?
Have fun...
