The San Leonardo in Treponzio is a Romanesque-style, Roman Catholic parish church, located along the road from neighborhood of Compito to the center of the town of Capannori in the province of Lucca, Tuscany, Italy.
In 1105, a church and hospital were founded to attend pilgrims in route south.
The layout is that of a Latin cross with a single nave and hemi-circular apse.
The original bell-tower was razed, and replaced at the same site by a new tower in 1894.
The facade has sculptural decoration attributed to followers of Guidetto.
