The name of the reserve, Genius Loci (Latin "Protective Spirit"), refers to the tradition of lucky, chosen places that possess their protective spirit. We believe that this Latin term suits best the unique nature of Ostrów Tumski, which for over 1,000 years has been inextricably linked with the history of our country and our city. Excavations carried out here since 2008 have uncovered well-preserved, impressively constructed medieval ramparts surrounding the stronghold located on the island. Thanks to the research we know that in the 10th century this place was bustling with political, economic and religious life. It was here that the most important decisions concerning the shape of the emerging state were made. The stronghold was incredibly modern for its time. The genius of the place brought together industrious and innovative people, who were able to put great ideas into practice, organise others around noble causes and inspire them with good ideas.
