San Mattia is a Roman Catholic parish church in Rome dedicated to saint Matthias. Designed by Ignazio Breccia, it is located on via Corrado Alvaro in the Monte Sacro Alto quarter. It has a marble altar, an olive-shaped sanctuary, a square overall plan and a 'sampietrini' floor made of cubes of porphyry. Seven grooves in the ceiling, converging on the presbytery, symbolise the seven sacraments.
