Santa Paolo Apostolo is a Roman Catholic church located on Via Bartocci in the town of Fiastra, province of Macerata, in the region of Marche, Italy.
The three rounded apses of the earlier Romanesque church were converted into a single square space.
The chapel of the Santissimo Sacramento has a rich stucco decoration, similar to the Bolognese church of Santa Maria delle Grazie.
The main altarpiece of the church was once a Conversion of Paul the Apostle by Giovan Battista Gaulli.
[1] The belltower was rebuilt in 1914 at the site of a former watchtower of an adjacent castle.
