In early Middle Ages, the shores of Lake Gop?o were home to a West Slavic tribe of Goplans. At the northern end of the lake stands the "Mouse Tower" of Kruszwica. Its name derives from a legend of the corrupt Prince Popiel, who fled to the tower from his rebelling population, and was devoured there by mice. Some historians and archaeologists consider the area the heart of the first state of the Polans, the "founding" tribe of Poland.
