Scenery - monastery or wizard's lair or something

This is one of the Meteora monasteries in Greece, occupied constantly since the 9th century. It would make an ideal isolated wizard's lair or something similar; the mists and the towering sandstone crags are certainly atmospheric.

The building itself is on two or three levels, and if you felt the need for more you could easily burrow down into the sandstone pinnacle on which it stands.
