Here's the gatehouse from the inner courtyard. There are two things in particular that impressed me about this castle. I was in awe at how solid it still was and how much had survived the centuries (and the weather). You can climb one of the towers and also completely walk along its upper ramparts.
Which leads me to the second thing - I don't think I've ever visited a castle that is situated in a more glorious setting; it just takes your breath away.
And to the north are the mountains in Snowdonia National Park.
This includes Snowdon, which is the highest peak in Wales. I think it's the pointy one glimpsed through the castle window. But more on that shortly.
