The greatest attraction of the village of Wąsowo is the Hardt family palace, built in the years 1870-72. In 1900, the Gothic Revival castle was expanded to the form we can see today. The estate is surrounded by one of the largest parks in Greater Poland, with plenty of nature monument trees. The park spreads on both sides of an elongated valley. The heart of the park is the pond and a valley with two clearings. The cache is hidden in the place with the greatest view of the palace and the park. Look around the tree visible on the last two photographs.
