The inside of Petra's most famous edifice—whose function during Nabataean times is still unknown—is surprisingly small. Possibly built in the first century A.D. during the reign of Aretas IV, Al Khazneh is one of more than 800 monuments in Petra. Much of the city is still underground, and nearly every stab of a shovel yields something new.
