Zocalo, Mexico City

The Zócalo Sits on the Exact Footprint of the Aztec Capital and the Ruins Are Still There Beneath the Square

The Plaza de la Constitución – universally known as the Zócalo – covers about 46,000 square metres, making it the second-largest public square in the world after Red Square in Moscow. It sits in the centre of Mexico City’s historic core on the exact location of the main plaza of Tenochtitlan, the Aztec capital that the Spanish demolished and rebuilt as Mexico City in the 1520s. The Metropolitan Cathedral to the north stands directly over demolished temple structures. The ruins of the main Aztec temple – the Templo Mayor – occupy the northeast corner, excavated from 1978 onwards after workers accidentally discovered the Coyolxauhqui Stone while laying electrical cables.

The Zócalo is not a preserved monument. It is a functioning public space: political demonstrations, military ceremonies, outdoor concerts, markets, and daily commuter traffic all happen here. On any given weekday morning you will find office workers crossing it, tourists photographing the cathedral, political banners on the government buildings, and everything else that constitutes a capital city square. There is no velvet rope around any of it.

What to See

The Metropolitan Cathedral is the largest cathedral in the Americas and took 240 years to build (1573 to 1813), which accounts for the mix of architectural styles across the facade – the bell towers are asymmetrical because different builders had different ideas across different centuries. The building has been sinking slowly into the soft former lakebed since construction. Monitoring equipment and hydraulic levelling systems are in continuous operation. Inside, the Altar de los Reyes at the far end is a high churrigueresque gold altarpiece from the early 18th century.

The National Palace on the east side contains Diego Rivera’s famous mural cycle depicting the history of Mexico, running along three walls of the central stairwell. Rivera worked on it intermittently from the 1920s to the 1950s. Entry is free. Bring binoculars; the upper sections contain specific imagery that is difficult to read from the ground.

Templo Mayor adjacent to the cathedral’s northeast corner is the excavated ruins of the main Aztec temple. The museum on site has a high-quality collection including the 3.5-tonne Coyolxauhqui Stone. Admission is around MXN 80.

Eating Near the Zócalo

El Cardenal at Palma 23 is the reliable choice for traditional Mexican breakfast and lunch – chilaquiles, mole, regional dishes cooked properly. It fills on weekends. The covered market at Plaza de la Constitución has stalls serving tacos, quesadillas, and comida corrida (set lunch) at prices that bear no resemblance to tourist restaurant pricing.

Getting There

The Zócalo has its own Metro station: Line 2 (blue line), stop name Zócalo. Cost approximately MXN 5. The surrounding streets – República de Brasil and Moneda in particular – have colonial architecture worth walking through.
