San Martino a Gangalandi, Renaissance church in Lastra a Signa, Italy.

San Martino a Gangalandi is a Renaissance church in Lastra a Signa with several chapels and a tall bell tower on its left side. The interior displays Renaissance features and adjoins a museum holding religious objects.

First documented in 1108, when Bernardo Adimari donated land to support the church and its canons, it was likely founded earlier under Carolingian influence, as the dedication to St Martin of Tours and Adimari patronage suggest. In 1278 it gained the baptismal font privilege after the Signa bridge collapsed. Leon Battista Alberti, rector from 1432 to 1472, designed its apse, completed between 1472 and 1478.

The parish church was also the seat of the Lega of the four popoli that became the Comune di Gangalandi, later Lastra a Signa. Its name comes from the Gangalandi family, linked to the Cadolingi counts, who held lands and a castle on the hill. The Museo Vicariale, founded in 1986 with financing from the Ente Cassa di Risparmio di Firenze, keeps a Madonna of Humility painted around 1405 by Lorenzo Monaco.

The building and its museum are accessed from Via Leon Battista Alberti, where the entrance is straightforward to find. Plan enough time to observe both the architectural details and the artworks displayed inside the museum.

The 15th-century baptismal font features carved marble details that showcase the craftsmanship of Renaissance sculptors. These fine details are often overlooked, though they reveal the high quality of sculptural work achieved here.
