Until a few years ago, it was the headquarter of the prisons, the female cloister of the Corpus Domini (built between 1466 and 1472) preserves only the boundary wall (the church was demolished in 1870) where some earthenware tiles are inserted (copies of them, the originals are kept in the Musei Civici). Attributable to the XV century is the Madonna, built in stone, in front of via mari. In 1783, the cloister was unified with the one behind, the cloister of San Tommaso, that would later give the name to the city prisons until their elimination, Currenty, in some rooms, there are the storehouses of the State Archives.
