This ornate door at San Martín Plaza leads to the former mansion of José C. Paz. In 1869, he founded La Prensa. This is still a widely-read daily Argentine newspaper. Flush with financial success, he hired French architect Louis Sortais to design Paz Palace. When completed in 1914, the 65,000 square feet qualified as the largest – and some say most opulent – residence in Argentina. In 1938, the property became Círculo Militar, a society of retired military officers.
