The territory became part of the emerging Polish state under its first ruler
Mieszko I around 967. Following the fragmentation of Poland, it formed part of the
Duchy of Pomerania. Towards the very end of the 12th century two settled camps or settlements have been established within the present-day town limits. Both of these settlements, with a mining and agricultural focus, were property of the
Bishopric of Kamien Pomorski. The first initial name of the town appeared in the 15th century as
Misdroige. According to sources, the early Slavic settlers were involved primarily in agriculture, cattle-breeding, fishing, bee-keeping and hunting. A wooden
pier on the Baltic Sea was constructed and eventually upgraded in 1906. The
pier was 360 metres in length and the coffee-house situated at its very end still operates to this day. In 1899, Misdroy was connected via railway with nearby
Szczecin and
Świnoujście, which contributed to an even greater number of patient and tourist arrivals. Shortly before the outbreak of
World War I, over 20,000 visitors were recorded, The town did not suffer destruction during the course of the war. After the war, the Międzyzdroje became part of the
Polish People's Republic in 1945 in accordance with the
Potsdam Agreement, and was granted town status. The town's Polish name comes from its original 16th-century meaning of the "town between salts springs", or Międzyzdroje in Polish. In 1959, town limits were expanded. ==Sights==
