Santissima Trinità (Holiest Trinity) is a late-Baroque architecture, Roman Catholic church and former monastery (Badia) located on Via Vittorio Emanuele, corner of Via Santissima Trinità in the city Catania, Sicily, southern Italy.
[1] Only after the 1693 Sicily earthquake, did the nuns move here and construction of the present church began soon after, in the 18th century.
The façade has a central concave protrusion, a Borromini-esque design attributed to Francesco Battaglia.
The first altar on the right houses a Baptism of Jesus by Olivio Sozzi (a copy of the painting by Vito D'Anna for the church of Origlione in Palermo).
The third altar houses a Madonna appearing to St. John the Baptist on Patmos attributed to Sebastiano Conca.
