Mangalia

25 miles south of Constanta

Built on the site where the city of Callatis stood 2,400 years ago and where ancient stone tombs, statues of gods and other artifacts have been found, Mangalia provides treatments for afflictions related to the kidneys, digestive and nervous systems, skin and liver. Its name comes from the Byzantine word Pangalia, meaning "the most beautiful," and it developed as a spa resort after the Second World War.

While in Mangalia, you can visit the Callatis Archeological Museum, the ruins of the Callatis Fortress (7th century BC), the Syrian Basilica and the 16th century Esmahan Sultan Mosque, the oldest mosque in Romania.
