The chronicles of the Teutonic Order mentioned the Castle of Merkenpille for the first time in 1377. It stood on a mound at a confluence of the Merkys, Nemunas and Stangė Rivers. Jogaila, the Grand Duke of Lithuania, visited the castle many times. Here, he gave the Magdeburg rights to the city of Vilnius in 1387. This is one of the most popular and most visited objects in all of Dzūkija. From the mound, you can see a beautiful panoramic view that includes the confluence of the Merkys and Nemunas Rivers as well as the surrounding forests.
