The Counts Choiseul-Gouffier administered the Plateliai Manor for 143 years. Four generations of this family lived here until 1940 when the wooden manor house was burnt down during the Second World War. One of the remaining buildings, the stone masonry granary of the 19th century, is the most attractive to the visitors. This granary offers several interesting exhibitions about the history of Plateliai and Plateliai Manor, Samogitian ethnography and the nature in this region. Some fascinating facts that can be discovered at the exhibition:
- The kind of boats used by the locals of Plateliai to cross the lake
- The kind of stone cannonballs used by the locals to fight the enemy
- Favorite kind of shoes of the Samogitians that were made from trees
- Traditional Samogitian cuisine
- Traditional Lithuanian sports game dating back to the 17th century, which is still popular in Samogitia
The visitors also learn about the smallest European bird which is encountered in the forests of the Samogitian National Park. This bird weighs from 4 to 8 grams, which is less than the 2-euro metal coin!
