Ustronie Morskie (formerly German Henkenhagen
Until the end of the 19th century, a fishing village. During the period of establishment of bathing resorts and sanatoriums, it slowly took on the character of a holiday resort. For some time, Ustronie Morskie was a very famous holiday resort. The dynamic development of the village began with the commissioning of the Koszalin-Kołobrzeg railway line in 1899, which enabled easy access from Szczecin and Berlin. The village received the rights of the commune in 1905. At that time, the Waterfront Palace (Almira) was built, demolished at the turn of 2007 and 2008.
The number of visitors was constantly increasing - in 1899 there were 360, in 1905 - about 1,200, shortly before the First World War about 3,000. In the 1920s, the resort was already one of the most famous bathing resorts in Germany. In 1939, 1,681 permanent citizens lived here in over 400 households.
Since 1945 it belongs to Poland, initially it was called Ustronie Nadmorskie. Over the last few decades, the tourist and leisure base has developed, a large number of holiday centers and sanatorium facilities have been established.
In the 1950s, as part of the construction of a coastal defense system, four coastal artillery battery posts were built in the coastal forest east of the village. The 31st Battery of the Permanent Artillery was established. Four Soviet 130 mm guns were mounted on reinforced concrete bases. They were to protect access to the Kołobrzeg port. In the years 1961–1965, the unit was cambered, decommissioned in the early 1970s, and the guns were left alone. A little further to the east, just beyond the Czerwona River, on the remains of former German roads and the buildings of the Luftwaffe rehabilitation center, the firing positions of the 42nd Missile Squadron of the 26th Gryfice Brigade of the National Air Defense Forces were built. In 1995 the squadron was disbanded. In 1996, the facilities were taken over by the Naval Technical Base. In the period of the Polish People's Republic, along the beaches, in the dunes, there were steel observation towers of the Border Protection Force equipped with large professional binoculars and marine radars.
