Church of Sant'Ambrogio, Catholic church in Legnano, Italy

The Church of Sant'Ambrogio is a church building in Legnano with a single nave, three cross-vaulted arches, and a barrel-vaulted apse. The interior walls create a unified space that flows from the entrance toward the altar.

The first documented mention of a church dedicated to Saint Ambrose in Legnano appears in the Liber Notitiae Sanctorum Mediolani of 1389, but the oldest part of the building may date to the mid-13th century, when Archbishop Leone da Perego was buried here in 1257. The present church was rebuilt from the foundations in 1590, keeping only the walls beside the altar and the bell tower, and was enlarged in 1740 to its current form.

The church displays significant artworks from the 17th century by Giambattista and Francesco Lampugnani, including frescoes and paintings of saints. These works by local artists shape the interior experience of visitors today.

The church is a place where visitors can spend time exploring the interior, though restoration work may affect access to certain areas. It is helpful to check ahead whether parts of the building might have restrictions during maintenance periods.

Archaeological excavations in 1992 uncovered pottery fragments from the 5th century beneath the church foundations. This discovery shows that human settlement existed at this location centuries before the documented church construction.
