The square was renamed in 1813 to honor the Spanish Constitution of 1812.
It originally functioned as the city's primary marketplace before urban modernization relocated commerce to nearby streets.
The Cathedral of Huancayo, located on the square, was established as a cathedral in 1944 but dates its architectural origins to earlier colonial structures.
The square is situated at an elevation of approximately 3,250 meters above sea level, impacting local weather patterns.
During the annual 'Fiesta de Santiago' in late July, the square serves as a hub for traditional dance and folk music performances.
Plaza de la Constitución serves as the primary urban heart of Huancayo, anchored by the Cathedral of Huancayo on its western edge. The square features a prominent central fountain and manicured garden beds surrounded by historic architecture and commercial storefronts. It serves as the site for significant regional civic ceremonies and public gatherings. The current layout retains a classic Peruvian plaza design with pedestrian pathways radiating from the center. It functions as a transit hub for foot traffic connecting the central commercial district to administrative buildings. The surrounding area remains the focal point for the city's cultural events and municipal celebrations.
