The museum is located in the south-west upstairs and wing and the downstairs rooms of the castle of the Batthyány family. The famous archives of the Batthyány family were once kept in the castle along with their weapon collection and library that was destroyed during WWII. The invaluable collection is part of National Collections, thus, we are only able to show a few pieces.

The permanent exhibition entitled 'Legacy of Generations' presents natural history, archaeological finds, history of guilds and cultural memoirs of the 19-20th century of the town of Körmend. Pieces of special interest are: finds in Körmend from the 14-15th century, Batthyány Ferenc parchment will from the 16th century, the guild jug of the butcher guild from 1726 velocipedes of the Udvari brothers from the 19th century and the exotic bird collection of Molnár Lajos.

A separate unit shows the life of the Blessed Dr. Batthyány-Strattmann László at the beginning of the exhibition.
