The Chiesa ed Ex Convento degli Agostiniani (Church and Former Convent of the Augustinians) - also known as the Chiesa dell’Ex Ospedale (Church of the Former Hospital), or Chiesa del Conventino (Church of the Little Convent) - was originally built at the end of the 15th century, at the behest of Caterina Pico, wife of Rodolfo Gonzaga, Marquis of Luzzara. It was later almost completely demolished and rebuilt between 1764 and 1771, although the apse fortunately remains from the original 15th-century structure.

In the sacristy, visitors can still admire the remains of a solemn funerary monument dedicated to Luigi Gonzaga, who died in 1570, partially destroyed by a fire in 1918. At its top, the monument displays the Gonzaga family coat of arms, upheld by two putti and surmounted by a crowned double-headed eagle. This ornament rests on a rich architrave supported by two massive mythological figures: a Caryatid and an Atlas. From the centre, beneath the cornice, supported by a lion’s head, a fruit festoon unrolls above the two figures, framing them within a square and ending in a broad base on which two eagles are placed. At the centre of the monument once lay the tombstone dedicated to Luigi Gonzaga, while beneath the adjacent portico, frescoes of significant historical and artistic value have recently been uncovered.

The convent, likely built by the Augustinians before the Church, followed a Romanesque layout - as evidenced by the portico and the surviving domical vaults that escaped later, less fortunate alterations. The fresco by Francesco Monsignori depicting the Madonna and Child with two saints, once housed inside, was sadly destroyed in the 1918 fire too. After the Augustinians left during the Napoleonic period, in 1824 Mary Louise - Duchess of Parma, Piacenza and Guastalla - decreed that the complex be converted into a hospital, a role it retained under the Lodigiani family, who acquired it in 1886. It was later donated to the Opere Pie (a charitable institution) of Luzzara, which managed it until 1978, first as a hospital and later as a nursing home. To the south, a more recent wing (built in 1948) merges with the ancient structure.

Following the suppression of local infirmary hospitals  after the construction of the Guastalla Hospital, the building - after further renovations - became the seat of the National Museum of Naïve Art (Museo Nazionale delle Arti Naïves). The entire complex, comprising both the Convent and the Church, was closed after the 2012 earthquake. The Museum it once housed will reopen soon within the new Civic Museum on Via Avanzi in Luzzara.
