Plaza Constitución (Constitution Square), Montevideo

Constitution Square, also known as the Main Square (Plaza Matriz), is the oldest city square in Montevideo. Situated in the Old City (Ciudad Vieja) neighborhood, the square has been a central part of the city since its establishment as the Main Square in 1726. It was originally the city's only open public space and has remained the heart of the historic district, encircled by significant structures such as the Metropolitan Cathedral and the Cabildo. This makes it a pivotal tourist destination.

The square itself was founded in 1726, shortly after the city of Montevideo, starting as a mere dusty plain. It wasn't until the late 18th century that buildings began to rise around it, transforming it into a venue for official events and celebrations, including bullfights, reflecting its cultural and social significance over the centuries.

In 1851, Constitution Square was redesigned with diagonal tree-lined paths, benches, and lanterns, enhancing its appeal and functionality. Its importance grew with the 1868 start of a project delivering water from the Santa Lucía River to Montevideo, involving a steam pump and a 60 km pipeline. A new fountain, created by architect Juan Manuel Ferrari and inaugurated in 1871 by President Lorenzo Batlle y Grau, featured griffins and national symbols around a circular pool and ornate column, becoming the plaza's centerpiece.

Today, Constitution Square continues to serve as a vital commercial and tourist axis within the Old City, flanked by pedestrian streets like Peatonal Sarandí. It is surrounded by a vibrant mix of offices, government buildings, banks, shops, and cultural institutions, remaining a focal point for both locals and visitors in Montevideo.
