Casa Blaquier excavations reveal colonial history in Buenos Aires

Archaeological excavations at Casa Blaquier in the Monserrat neighborhood of Buenos Aires have uncovered significant historical artifacts and structures. The site, located at Defensa 163, was recovered by the Government of the City of Buenos Aires following approximately four decades of irregular occupation.

Key findings include two colonial coins (macuquinas) dated 1743 and 1749, a bone-carved chess piece, and over 4,000 fragments of porcelain, ceramics, glass, and majolica. Researchers also recovered kaolin pipes, marbles, beads, buttons, and animal remains, providing insight into the domestic life and diet of former residents.

Multidisciplinary teams of archaeologists and paleontologists have identified five distinct historical structures, including a six-meter-deep latrine built with mud-bonded bricks, a sewage sink with a brick vault, discard pits, and an unexcavated cistern that still contains water.
