Another important Roman quarry complex in the heart of the Eastern desert, Mons Porphyrites yielded Imperial Porphyry, a superb purple rock found nowhere else in the world. Much of this gem-like rock was made into pillars, basins, statues and sarcophagi for the glory of Rome and Istanbul. You can explore the remnants of fortress ruins, dwellings, temples, wells, shrines, broken pillars and cracked stone baths.
