Laurence, the Officers' Mess was indeed the circular fort building featured in so many pictures. The top floor was one bedroom occupied by the resident Squadron commander. The next floor down comprised the anteroom and dining rooms, both quite small, and 2 (I think) other bedrooms. Outside, at that same level, was a walkway around the building and, on the north side , again at that level, there was a small pool for lying in with a beer, or three. The pool was usually a bit tepid and an alternative was one of the several falaj-fed pools aound the oasis of which the best was over in Muweiqi (pronounced Muweiji). They were always cool as the water flowed underground from the mountains to the East.
