Sant'Oliva ("Saint Olivia") is a catholic church located in Alcamo, province of Trapani, Sicily, southern Italy.

[4] In 1724, the church was rebuilt in the present form, with a longitudinal plan that had one nave, after the design of Giovanni Biagio Amico,[1][5] an architect from Trapani.

[7] During the night of 7–8 August 1987, a fire destroyed the ceiling of the church; it was rebuilt some years later thanks to the Sovrintendenza ai Beni Culturali of Sicily.

[9] The church has two portals: the main one overlooks piazza Ciullo, while the other one, with the statue of Saint Olivia on it, faces Corso 6 Aprile.

Initially, there was a main portal dating back to 1572,[1] but after the acquisition of some funds in connection with the Great Jubilee, both doors were replaced by two golden bronze ones realized by Vincenzo Settipani, an architect.
