Opinogóra is associated with one of the three main Polish poets of the romanticism period - Zygmunt Krasiński. His most widely known book is entitled "Nie-Boska Komedia" ("Non-Divine Comedy"). Zygmunt was givien Opinogóra and 40 surrounding villages by his father, gen. Wincenty Krasiński.
General Krasiński built a large park and a small castle for his son Zygmunt, as he wanted him to return to Poland from Switzerland. The bait was also his old love, Amelia Załuska. When Zygmunt returned, Amelia waited for him sitting on a stone bench with a romantic insription. However, Amelia's duty was to convince Zygmunt to get married with Eliza Branicka... In fact, Zygmunt married Eliza and it was a happy marriage.
All will easily find the castle, the house, the bench and the church with Krasinski's tombs. The cache will thus lead you to a less frequently visited but quite romantic park. The cache can be found under the ground (but not buried).
