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 an interesting exhibit on comics, and a high-profile exhibit on Stanisław Wyspiański (whose epic monument stands outside the entrance); see our What's On section for more details. The main branch also currently exhibits one of the museum's most cherished treasures - Leonardo da Vinci's famous oil painting Lady With an Ermine; beloved by locals, the painting is displayed in its own separate room, to which visiting is limited to 20 individuals at a time and a separate ticket is required (20/15zł). 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.
