The Chiesa di San Giovanni Battista is a Gothic church built between the 13th and 14th centuries, ranking amongst Monterosso al Mare's most significant monuments. Its striking façade features alternating white and green marble with a central rose window dating from 1307. The bell tower is a converted medieval watchtower, a remnant of the town's defensive past. Located on the main piazza overlooking the harbour, it remains a focal point of this charming Cinque Terre village.
