A 10-minute tram ride from Piazza del Popolo allows you to leave the Renaissance far behind and MAXXI, a masterpiece of contemporary architecture with bending and overlapping oblong tubes designed by Anglo-Iraqi architect Zaha Hadid. The museum is divided into two sections, MAXXI art and MAXXI architecture, primarily serving as a venue for temporary exhibitions of contemporary work in both fields (although it does have a small and growing permanent collection). The building is worth a visit in its own right.
