Plaza Matheu, Public square in La Plata, Argentina.

Plaza Matheu is a public square in downtown La Plata with stone paths, grass areas, and a central monument located at the intersection of Avenida 1 and 66. A mix of pine, lime, ash, araucaria, and cypress trees distributed across the grounds provides shade and defines the space's natural character.

Named in 1901 after Domingo Matheu, a Spanish-born politician who sat as a vocal on the First Government Junta of 1810. The monument to Matheu in the centre is by sculptor Pietro Costa and previously stood in Plaza San Martín, as part of the Monument to the First Junta, before being moved here.

The square serves as a gathering point where residents and visitors move through shaded corridors formed by mature trees and spend time on open lawns. People naturally drift toward the monuments and quieter corners, making it part of daily life in La Plata's downtown.

The plaza is easily walkable and situated at a well-connected location with multiple bus lines nearby serving the area. Paved paths run through the space, making it convenient to explore on foot without needing a vehicle.

The Matheu monument in the centre was made by sculptor Pietro Costa and once stood in Plaza San Martín as part of the Monument to the First Junta before being moved here. Two bocce courts run by the group "Amigos y jubilados de la plaza Matheu" operate in the square.
