Nice. I have visited many castles in the UK in the past. Some look like new, but many are just ruins.
I've visited a few in the UK, and a few here in Spain. There's one really close to me which I've been a number of times: https://en.wikipedia.org/wiki/Palace_of_the_Kings_of_Navarre_of_OliteWe also visited this one some years ago: https://en.wikipedia.org/wiki/Castle_of_LoarreAs well we've visited a few other miscellaneous old structures such as churches and monasteries. I have a pile of photos too, but would take me ages to cherry pick...
Nothing ever beats the sheer castleness of British or Irish castles!
