SFA did I miss something? why are you invading England if Chepstow Castle is in Wales? Truly glorious, wherever it may be!
*** Oh I just watched the video SFA, and the castle is of the legacy of William the Conqueror, begun 1067!
Oh and I am (mentally) adding all these fascinating places into the itinerary when Tink and I come to visit Wales with you, starting with that huge rock from the order of Stone Circles...of course we must not omit the smallest house in Great Britain, after going through this castle....and we will want to go through some tunnels, too...
