San Nicolò, minor basilica in Pietra Ligure, Italy

San Nicolò is a baroque basilica on Piazza San Nicolò in Pietra Ligure, built from 1752 to a design by Genoese architect Giovanni Battista Montaldo. Its single nave is 56 m long and up to 27.50 m wide, with a 25 m-high pavilion vault covering 23.50 × 27.50 m, one of the largest in Europe. Six side chapels line the nave, and the facade has three bronze portals by Andrea Monfredini (1986–1992) between two three-storey bell towers.

Construction began in 1752, following a plague miracle attributed to Saint Nicholas in 1525 that inspired the community to build this church. The project took about 40 years to complete, with the building blessed in 1791.

Every 8 July a procession through the streets marks the end of the 1525 plague, which the town attributed to Saint Nicholas. A handprint on a bell of the old parish church, the Chiesa madre, is still shown as the "hand of Saint Nicholas". The church keeps a wooden icon of the saint painted by Giovanni Barbagelata in 1496, restored in 2010 and placed in the apse.

San Nicolò stands on Piazza San Nicolò, facing the seafront just beyond the old town. The main entrance is the central bronze portal by Andrea Monfredini, installed in 1986; two smaller doors flank it. Inside, the single 56 m nave and its 23.50 × 27.50 m vaulted ceiling are seen at their best in daylight.

The 1496 icon of Saint Nicholas on wood, painted by the Genoese artist Giovanni Barbagelata, hangs in the apse and was restored in 2010. The church keeps 14 bells across the four bell chambers of its two towers; the four in the lower chamber of the forward tower announce services.
