Casa de Esteban de Luca, Colonial residence in San Telmo, Buenos Aires, Argentina.

Casa de Esteban de Luca is a late-18th-century colonial house at Carlos Calvo 383 in San Telmo, with its original facade still standing while the interiors date from the late 19th century. It keeps a portion of two-slope tiled roof, a narrow door, two windows and a plain, unornamented front. Inside were two rooms and a small patio.

The building dates to 1786, when Buenos Aires was establishing itself as a prosperous colonial city under Spanish rule. It survived the turbulent early decades of the 19th century, including foreign military conflicts that reshaped the region.

Esteban de Luca wrote odes to General José de San Martín and to the battles of Chacabuco and Maipú, and his Marcha Patriótica served as Argentina's unofficial national anthem until 1813. He also directed the National Munitions Works during the War of Independence and lived here until his death in 1824.

The building is located on Carlos Calvo Street in San Telmo and now operates as a restaurant where visitors can experience the historic surroundings while dining. It is easily accessible on foot and works well as a stop during a walk through this historic neighborhood.

The house was declared a National Historic Monument in 1942, not 1941 as often repeated; the English Wikipedia gives 1941. From 1982 a shoe shop on the corner of Defensa Street became a colonial-themed restaurant, La casa de Esteban de Luca, which annexed the house on condition that the interiors stay unaltered; it operated until 2008.
