Pamukkale is a natural site famous for its hot springs and enormous white terraces of travertine, a carbonate mineral left by the flowing water. Because of its natural beauty it is Turkey's foremost mineral-bath spa. Pamukkale, meaning Cotton Fortress in Turkish, has been a spa since the Romans built the spa city of Hierapolis around a sacred warm-water spring. The Antique Pool is still there, littered with marble columns from the Roman Temple of Apollo. Overshadowed by natural wonder, Pamukkale is also well-preserved Roman ruins and museum. Visiting Pamukkale can include exploring the Roman ruins of Hierapolis, climbing the ranks of seats in the great Roman theater, touring the exhibits in the Archeological Museum, splashing along the travertines and even soaking in the Antique Pool.
