The Alytus Ethnography Museum is the town's best compact introduction to Dzūkija culture and local history. Its collections cover folk life, crafts, photographs, and domestic objects, putting Alytus into the wider story of southern Lithuania rather than presenting it only as a river town.
It is a modest museum, but useful if you are trying to understand the region's timber, village, and borderland background. Go before walking the Nemunas riverbanks or the old town streets, and the everyday objects on display will make the landscape feel less anonymous.
