San Leonardo is a Romanesque-style Roman Catholic church in the town of Borgomanero, province of Novara, Piedmont, Italy.
Traces remain of frescoes depicting Christ Pantocrator with the symbols of the Evangelists, the twelve Apostles, the months of the year, a series of saints; and a Last Supper with Judas' Betrayal.
Finally, the church also has a 16th-century fresco, also by an anonymous painter, depicting the Madonna of the Sette Dolori.
[4] The oratory has a single nave of about 12x7m, divided into three rectangular bays and covered by a cross vault whose ashlars are still preserved inside and the buttresses outside.
The façade is gabled, in square blocks of stone, with a door surmounted by a lunette and a small cross-shaped window.
