Yerebatan Saray? translates as “Sunken Palace.” It’s Istanbul’s largest underground cistern - a remnant of the Romans - and the only one renovated and opened for public viewing. Today Yerebatan Saray? is a major tourist attraction and offers a cool respite from Istanbul’s searing summer heat.
Pulsing lights, water dripping from the ceiling and eerie music played over strategically placed speakers add an air of mystery to the place. Note the two large Medusa heads supporting columns on the north side of the cistern. Wooden walkways allow visitors to view the whole cistern. A small entrance fee applies.
