Housed inside a glorious neo-Renaissance former hotel and having its roots in the 1920s, this three-floor diversion offers glimpses into the region's archaeology, ethnography and history by way of a number of temporary and permanent exhibitions. As well as the usual glass cases full of bones and pots, particularly outstanding and not to be missed is the Polish Art collection, showcasing some of the finest Polish artists of the 19th and 20th century, including no less than five paintings by the country's great creative genius Stanisław Wyspiański.

Admission 12/7zł for all exhibits, 9/5zł for temporary exhibits only, 6/4zł for permanent exhibits only. Sat free for permanent exhibits.
