In hotels in the Middle East or otherwise likely to be catering for lots of Muslims you'll find on the dressing table a little sticker with an arrow indicating the direction of Mecca.

Christian burials in Britain from Roman times have been East-West, with the head at the west, so you face west when reading the headstone. My father was buried in a cemetery oriented that way; he was cremated, but even then his the memorial stone - laid flat, rather than vertical - is oriented so you face west when reading it, even though, for the relatives of the first people in that burial ground, it is a bit awkward as you have to stand jammed up against a hedge and with your feet practically on the stone.
