Mons Porphyrites information
This is the site of ancient porphyry quarries worked by the Romans. The precious white-and-purple crystalline stone was mined and then transported across the desert along the Via Porphyrites to the Nile for use in sarcophagi, columns and other decorative work elsewhere in the Roman world. The quarries were under the direct control of the imperial family in Rome, which had encampments, workshops and even temples built for the workers and engineers here. Evidence of this quarry town can still be seen, although not much of it is standing.
To get here, you will travel about 40km northwest of Hurghada; a road leading to the site branches off the main road about 20km north of Hurghada. Tours can be easily arranged in Hurghada.
