Tadeusz Kościuszko is a beloved Polish figure who fought in the American Revolutionary War and later inspired the Kościuszko Uprising against foreign rule in Poland. Like the ancient Krakow mounds built to commemorate the legendary King Krakus and Princess Wanda, this verdant mound was made to honor the modern-day freedom fighter. The structure holds urns with soil from the Polish and American battlefields where Kościuszko fought.
Visitors enter the mound through a museum built into the surrounding brick fortifications and featuring a permanent exhibition on Kościuszko. A winding path leads to the top, where visitors will find a granite boulder inscribed with "Kościuszce" (To Kościuszko), as well as spectacular views of the city, the Vistula River, and the distant Tatra Mountains. On-site is also the Chapel of Blessed Bronisława, a neo-Gothic structure with additional artifacts related to Kościuszko.
