I am sharing this photo with you even though I personally have reservations about it. The reason being that it looks like the cannon is aimed at Caldey Island. A totally stunning Island which is the home of a few monks that run the island... and make their lives from there. It is the most peaceful and beautiful place in Pembrokeshire I have been to, and that is why I do not like the idea of a cannon aimed at it (even though the cannon is one of four all pointed in different directions so not purposely aimed at the island) But if you forget all that it still is quite a nice shot.
