The old granary and stable of the former Plateliai Manor now houses a highly worthwhile museum complex. The granary holds a multistorey exhibition dedicated to the nature, history and ethnography of the area, as well as archaeological findings from Sventrokalnis and Pilies islands on the lake. The stable houses a fascinating exhibition of local Shrove Tuesday Carnival customs, complete with around 250 (scary) masks. Hours and entrance fees contract in winter.
