The city borders on Chełmska Hill (Polish: Góra Chełmska), 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.
