It is commonly known as Piazza San Rocco because the church dedicated to the patron saint of Cercemaggiore against the plague faces it. The church dedicated to him received that title after the plague of 1656-1657. Inside, in addition to the 18th-century marble altar, there is a wooden statue of the Immaculate Conception made in 1766 by Paolo Saverio Di Zinno. Standing out on the square is a column surmounted by the cross, made of stone, placed there by the municipality in 1569 to commemorate a ruined church dedicated to St. Peter; carved on the base pillar is the oak tree symbolizing the municipality and engraved with the dates of both construction and restoration, the latter of which took place in 1844. On the same square is a monumental fountain bearing the construction date of 1910.
