Santi Gervasio e Protasio Church, Catholic parish church in Trezzo sull'Adda, Italy

Santi Gervasio e Protasio is the parish church of Trezzo sull'Adda, built between 1362 and 1370. Its facade and bell tower were rebuilt in a neo-medieval style by architect Gaetano Moretti in the early 20th century; the tower was erected between 1907 and 1910.

Built between 1362 and 1370, the church was elevated to pieve by Archbishop Federico Borromeo in 1604, when its vicariate included Basiano, Busnago, Concesa, Colnago, Cornate, Grezzago, Pozzo d'Adda, Trezzano Rosa and Vaprio d'Adda. It was enlarged in 1609, and in 1992 it was restored again.

The name honors two early Christian martyrs whose veneration spread widely during medieval times. The community continues to use the space for religious celebrations and local gatherings, showing how central this place remains to village identity.

The church stands in Trezzo sull'Adda, in the metropolitan city and archdiocese of Milan, and belongs to the deanery of Trezzo sull'Adda. It follows the Roman rite rather than the Ambrosian rite used in much of the archdiocese. The facade and the bell tower, both rebuilt in neo-medieval style in the early 20th century, are the elements to look for from outside.

The facade and bell tower are both 20th-century works by Gaetano Moretti, rebuilt in a neo-medieval style: the facade in the early 1900s, the tower between 1907 and 1910. The medieval origin of the church lies in the 1362-1370 construction, not in these visible elements.
