Basilica di San Vittore al Corpo

Unlike il Duomo, you’re unlikely to find tourist queues here. The facade of the Late Renaissance structure is totally unassuming but the interior is breathtaking. It has an incredibly ornate panelled arch in its main nave with illustrations of those saints whose remains are supposed to be housed here. Its magnificent dome is covered in gilded stucco and frescoes by celebrated Milanese artist Daniele Crespi. Climb the bell tower and enjoy a mesmerizing view over the city.
