MAXXI – National Museum of 21st Century Arts

Italy's leading contemporary art and architecture museum, designed by Zaha Hadid and opened in 2010 — the building won the RIBA Stirling Prize that same year. Sweeping concrete curves, suspended staircases, and dramatic interior flows make the architecture as much an attraction as the rotating exhibitions. In the Flaminio district, just north of the historic centre. Closed Mondays.
