Glacial erratics in Kołbacz, were collected from the local fields. It was done by the Experimental Unit of the Zoo-technology Research Institute, whose main task was to make academic research and to raise and breed cattle, swine, and sheep. Władysław Mazurkiewicz, who had been the manager of this institution for many years, was also a great fan of Kołbacz. He initiated transport of the biggest, erratic in the collection from Dębina on Miedwie Lake. Erractics are kind of natural monuments. On some of them, memorial plaques are installed. They concern important events from the history of the town and the whole region.
In 1973, the abovementioned glacier erratic from Miedwie, added splendour to the celebrations of the 800th anniversary of the arrival of the Cistercians to Kołbacz. It is a big-size, red-brownish Rapakivi granite which came from the Aland Islands on the Baltic Sea. It has 9 meters in perimeter and it is 2,2 meters tall. It weights approximately 40 tons. As a monument of nature it has been under special protection. Another erratic, which is also of impressive size (perimeter 10,4 m, height 1,55 m), commemorates Western Pomerania’s return to Poland. The plaque was added in 1985, on the day of the 40th anniversary of that important event. One of the smallest stones has a logo of the Experimental Unit of the Zoo-technology Research Institute. The plaque was made in 1987, to celebrate the 20th birthday of this institution.
