Visiting Wales - Caerphilly Castle
Caerphilly Castle is the largest in Wales and one of the largest in Europe. It has been the centre of many battles and has some amazing defenses (see the second picture). You can see much of the results of attacks on the castle, one tower leans further than the tower of Pisa, and another tower has been completely destroyed. One of the most amazing features was the grand hall. It was at least 4 stories high and the windows were enormous.
