At 120m by 120m, Plaza Mayor is one of the largest town squares in the Americas. It's paved with massive cobblestones and surrounded by magnificent colonial structures and a charmingly simple parish church. Only a small Mudejar fountain in its middle, which provided water to the village inhabitants for almost four centuries, interrupts the vast plaza. Unlike most Colombian cities where the main squares have been named after historic heroes, this one is traditionally and firmly called Plaza Mayor.
