• Langweil's paper model of Prague, 20 m² and over 2,000 pieces, built over 11 years from 1826; half the buildings on it no longer stand
• Not step-free for now, since works on Florenc metro station have left the museum without barrier-free access, so plan for stairs with a stroller
• Grifé Bistro inside the building, with coffee, desserts, sandwiches, burgers and semolina porridge for a mid-visit break

The main building of the Museum of Prague reopened after a five-year renovation, with new technology inside a 1900 building. Kids get a bird's-eye flight over 19th-century Prague in an immersive hall, life-size "living pictures", and Antonín Langweil's 20 m² paper model of the city, where they can hunt for familiar streets.

An AI portrait of Langweil talks back, and Grifo, the museum's griffin, talks only to kids.
