Santa Barbara church, Catholic church in San Donato Milanese, Italy.

Santa Barbara is a parish church at the centre of Metanopoli, the ENI company settlement in San Donato Milanese. Its gabled facade, recalling Tuscan cathedrals in colour, has a base portico sheltering three entrance portals, the central one designed by Arnaldo and Giò Pomodoro. Inside is a single nave with a narrow transept, lit at the presbytery by an upper skylight.

Santa Barbara was designed in the early 1950s by ENI's company architect Mario Bacciocchi as part of Metanopoli, the settlement built for the headquarters of the Ente Nazionale Idrocarburi and its housing. Construction was completed in 1954, and the church was erected as a parish in 1963 to serve a community that was growing steadily in population.

The church is named for Saint Barbara, patron saint of mining and therefore of ENI's hydrocarbon research and production. Inside, the ceiling panels are by Andrea Cascella, the Via Crucis by Pericle Fazzini, the Madonna della Speranza altarpiece by Bruno Cassinari, the Sant'Antonio chapel by Franco Gentilini, and the apse mosaic of the Crucifixion by Fiorenzo Tomea.

The church stands at the centre of Metanopoli, facing a wide square, with the parish house, baptistery and bell tower alongside it. The three entrance portals sit under a portico at the base of the facade, the central one designed by the Pomodoro brothers. The presbytery is lit from above by a skylight.

The apse mosaic of the Crucifixion by Fiorenzo Tomea is the third-largest wall mosaic in Europe and the largest in Italy. The central portal was designed by the brothers Arnaldo and Giò Pomodoro.
