The Church of St Augustine, also known as the Church of Santa Maria Liberatrice, was erected in 1630 by the Municipality of Pinerolo as a tribute to the Virgin Mary to express gratitude for the interruption of the plague during the second French domination. Its architecture presents a simple rectangular façade, perhaps begun but never completed: two pilasters emphasise a marked verticality, partially limited by a horizontal frieze. Its internal structure is also basic and uncluttered. Among the valuable works preserved, the stucco high altar deserves special mention. Also of interest is a canvas depicting the Virgin Mary protecting Pinerolo from the plague. Today, the church no longer hosts religious worship, but is a venue for exhibitions and cultural events.
