Ten minutes north of Piazza del Popolo by tram, leave the Renaissance far behind at MAXXI, a masterpiece of contemporary architecture with bending and overlapping oblong tubes designed by the late 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 permanent collection). The building is worth a visit in its own right.
