Just back from a short break on Anglesey. On the way we stopped, as usual, at a National Trust property for a break. This time it was Penrhyn Castle. The castle itself is well preserved, as are so many in Wales, and this area of North Wales is renowned for its slate. Penrhyn has a slate splitting demonstration on site. Hopefully you can see from the photo, this guy managed the seemingly impossible, splitting a slate which was already only about 3mm thick.
