San Maurizio al Monastero Maggiore, a church in Milan, is renowned for its rich history and artistic significance. Originally part of the most important Benedictine female convent in Milan, it now houses the Civic Archaeological Museum. The church is celebrated for its stunning 16th-century frescoes that cover its walls and the unique feature of being divided into two parts: one for the faithful and one for the nuns. This architectural marvel is not only a place of worship but also serves as a concert hall, blending the sacred with the cultural in the heart of Northern Italy.
