Asklipio

This guide to the hilltop fortress above Asklipio on Rhodes turns on a single calculation the Knights of Saint John made when Grand Master Pierre d'Aubusson's builders strengthened an older Byzantine site in the 1470s: with no spring or stream nearby, water mattered more than walls. You'll hear how they built two vaulted cisterns, one in the courtyard and a second inside the outer barbican, so an attacker who breached the first line still couldn't starve the garrison out. The guide also follows the dry moat that once ringed the northern side, now just a dip in the ground.
