The city of Al Hajjara in Republic of Yemen* Haraz Mountains looks ancient yet modern at the same time: the taller of the brown, flat-roofed houses so precariously balanced on top of the mountain resemble early skyscrapers.

The town’s remoteness and narrow streets suggest a closely knit community that could, in times of invasions, have allowed outsiders to enter yet not necessarily to leave
