was the first post-war regional capital of Polish Western Pomerania, before the administration finally moved to Szczecin in February 1946, after which the region was named the Szczecin Voivodeship. In 1950 this voivodeship was divided into a truncated Szczecin Voivodeship and Koszalin Voivodeship. In years 1950-75 Koszalin was the capital of the enlarged Koszalin Voivodeship sometimes called Middle Pomerania due to becoming the fastest growing city in Poland. In years 1975-98 it was the capital of the smaller Koszalin Voivodeship. As a result of the Local Government Reorganization Act (1998) Koszalin became part of the West Pomeranian Voivodeship (effective 1 January 1999) regardless of an earlier proposal for a new Middle Pomeranian Voivodeship covering approximately the area of former Koszalin Voivodeship (1950–75). In 1991, Koszalin was visited by Pope John Paul II. On the fifth anniversary of his visit, his monument was unveiled in the city center. Landmarks The city borders on Chełmska Hill (), a site of pagan worship in prehistory, and upon which is now built the tower "sanctuary of the covenant", which was consecrated by Pope John Paul II in 1991, and is currently a pilgrimage site. Also an observation tower is located on the hill. At the entrance to the sanctuary there is a monument dedicated to the Polish November insurgents of 1831, who, imprisoned by Prussian authorities, built a road connecting Koszalin with nearby Sianów. Koszalin's most distinctive landmark is the Gothic St. Mary's Cathedral, dating from the early 14th century. Positioned in front of the cathedral is a monument commemorating John Paul II's visit to the city. Other city landmarks include the Park of the Dukes of Pomerania (Park Książąt Pomorskich), the Koszalin Museum, the main post office, the 16th-century Wedding Palace and the Culture Centre 105 (Centrum Kultury 105). The city also has monuments dedicated to Polish national heroes: Józef Piłsudski, Władysław Anders, Kazimierz Pułaski, Władysław Sikorski, as well monuments of the 19th-century Polish poets Cyprian Norwid and Adam Mickiewicz. Climate The climate is oceanic (Köppen: Cfb) with some humid continental characteristics (Dfb), usually categorized if the 0 °C isotherm is used (for the same classification). Being in Western Pomerania and near the Baltic Sea, it has a much more moderate climate than the other large Polish cities. The summers are warm and practically never hot as in the south and the winters are often more moderate than the northeast and east, although
