San Leonardo da Porto Maurizio is a modern parish church with its postal address at Via Ludovico Antomelli 1, which is in the suburb of Acilia Sud to the south of the Via del Mare on the way to Ostia. Acilia trains station is to the north-west. The main entrance is round the corner in Via Daniele da Samarate.
The parish is administered by the Franciscan Friars Minor, and the patron saint was Leonard of Port Maurice , a famous Italian Franciscan home missionary who established the Stations of the Cross in the Colosseum and who died in 1751.
The church was designed by Francesco Fornari, and built in 1936 in the neo-Romanesque style. There is an external semi-circular apse, and a small round baptistery on the right hand side near the entrance with a low conical tiled roof and a lantern with window slits. Also, there are two little semi-circular chapels attached to the left hand side wall. The attached narthex is windowless and gabled, with a stone string course halfway up (this is continued on the nave frontage behind) and a slightly recessed arched doorway surrounded by three orders in tiles laid with the edges showing. Above the door is a stone tablet bearing a dedicatory inscription, than a smaller tablet with a papal coat-of-arms, then a round window with a tile frame just below the gable.
At the corner of the church to the left of the apse is a simple square brick tower campanile with a pair of arched soundholes on each side.
The narthex, baptistery, apse, chapels and campanile are in pink brick. The side walls of the nave are rendered in a reddish orange, with brick pilasters and with arched narrow arched windows.
There is a bronze statue of the patron saint outside the narthex, to the left.
