This vast Roman site and important landmark is named after Mons Claudianus, who was once a provider of grey granite for the Roman Empire. One thousand quarrymen and Roman soldiers were stationed in this part of Hurghada for over two centuries. Superb objects can still be seen today in the Pantheon, Hadrian's Villa and in the unfinished Temple of Venus. Other sights include the fortress, dwellings, workshops, stables, baths, broken granite columns and slabs.
