The castle is a mound of rubble about the size of the Pentagon. The lee corner has been fitted out with a functional roof, electrical wiring, and a few other frills such as doors and windows. In this area, which is all Waterhouse gets to see for that first afternoon and evening, you can forget you are on Outer Qwghlm and pretend that you are in some greener and balmier place such as the Scottish Highlands.
