The National Museum has 11 branches in Kraków, with this monolithic structure - apparently built over the course of half a century from 1935 to 1989 - being the main administrative branch and landing spot for the institution's most ambitious exhibits. Permanent exhibits include the Gallery of Weaponry & Uniforms and Gallery of Decorative Arts, but it's the consistently excellent temporary exhibits that should lure you here. Currently you'll find a high-profile exhibit on local son Stanisław Wyspiański (whose epic monument stands outside the entrance) - one of the most important artists of the turn of the 20th century. One of Kraków's largest museums, you'd be wise to focus on what you're most interested in; to see it all would take the entire day. The museum also houses a small shop and cafe.
