The Druskininkai Castle Site is one of the best places to see the city. Peoples always enjoyed coming here and watching the bend of the Nemunas river. During the interwar period, the place was especially popular with the Polish Marshal Jozef Pilsudski who'd come here and spend hours and hours sitting and looking into Lithuania on the other side of the shore. Historians in the 19th century claimed that a well fortified wooden castle was built here in the 13th century to help the lithuanians defend themselves from the Crusaders. This is confirmed not only by inscriptions, but also by the finds of Teodoras Narbutas that were discovered in 1826 at the bottom of the hill, near the Nemunas river, and an excavated burial ground located nearby.

However today it's impossible to verify these statements, as the mountain was significantly damaged by a flood that occured in 1841. Druskininkai was damaged by the current with several bridges and a number of villas. The flood also expanded and deepened the bed of Ratnyčėlė river, and washed a large part of the hill into the Nemunas.
