San Mattia, Bologna

San Mattia was a former Roman Catholic monastery and church located at 14 via Sant'Isaia in Bologna, region of Emilia Romagna, Italy.

An earlier church was built just outside the Porta Saragozza for nuns from the San Mattia convent, a group of nuns originally derived from the Santa Maria del Monte della Guardia, who were guardians of the Basilica of San Luca.

The new convent's church was built between 1575 and 1588 by Pietro Fiorini to plans by Antonio Morandi, known as Il Terribilia.

In the 1830s the city council converted the convent buildings into a school, which it still is today, whilst the church was deconsecrated and used as a warehouse until the end of the 1970s.

The church and part of the monastery buildings were then sold by the city council to the Sovrintendenza per i beni architettonici dell'Emilia Romagna.
