Chiesa di Santa Croce, Catholic church in Populonia, Piombino, Italy

Chiesa di Santa Croce is a 15th-century church in Populonia, in the municipality of Piombino. It has a single nave, and to the left of the entrance a fragment of fresco survives, held to be what remains of the church's original decoration, probably by Sodoma.

The church was built in the 15th century in Populonia, in the territory of Piombino. It was later reduced to a single nave. A fresco fragment by Sodoma, a friend of Jacopo V Appiani, lord of Piombino, survives left of the entrance. A 17th-century wooden crucifix kept here was moved to the cemetery chapel and in 1995 to the Museo civico-diocesano of Piombino.

A fresco fragment left of the entrance is held to be what remains of the church's original decoration, attributed to Sodoma, a friend of Jacopo V Appiani, lord of Piombino, who sometimes stayed in Populonia. The church also probably housed a 17th-century wooden crucifix, moved to the cemetery chapel and in 1995 to the Museo civico-diocesano of Piombino.

The church stands in Populonia, in the municipality of Piombino, on the Tuscan coast. It is a single-nave building entered from the street; the fresco fragment is to the left of the entrance, so look there first. The 17th-century wooden crucifix once kept here is now in the Museo civico-diocesano of Piombino, not in the church.

A 17th-century wooden crucifix once kept here was moved to the small cemetery chapel and then, in 1995, transferred to the Museo civico-diocesano in Piombino, so the church's best-known artwork is now seen elsewhere in town.
