Mangalia is a coastal tourist city and a well-known spa resort located in the southern part of the Romanian Black Sea coast. Mangalia was originally a Greek colony called Callatis which become an important economic hub during the Hellenistic period. Over the centuries, Callatis was occupied by the Roman and Byzantine empires.
During the 1950s the city became the first Spa Center in Romania due to its thermal sulfurous springs. A harbor and shipyard were also built, making it the second harbor, after Constanta Harbour, to be situated along the Romanian coast.
