The old signal box

We decided to go for a walk along the Menai Straits to Llanfair PG (the one with the long name) but when we got down to the shore the tide was in up to the rocks at the edge so we had to do a bit of scrambling over them and just to make it more interesting they were covered with wet slippery seaweed.
We managed to get up to road in one piece passing over an old railway line on the way where this pretty little signal box was.
