Discover more about Palacio San Martin

The Palacio San Martin, located in the Retiro neighborhood of Buenos Aires, is a remarkable example of Beaux-Arts architecture. Designed by Alejandro Christophersen and completed in 1909, it was initially commissioned by Mercedes Castellanos de Anchorena as a family residence. For two decades, it was known as Palacio Anchorena, hosting lavish social gatherings, including the commemoration of Argentina's Independence Proclamation centenary in 1916. In 1936, the Argentine government acquired the palace and transformed it into the headquarters of the Ministry of Foreign Relations. In 1993, the Ministry's administrative functions were moved to a modern building nearby, and the Palacio San Martin became its ceremonial headquarters. Today, it hosts important events, meetings with foreign leaders, and state ceremonies. The Palacio San Martin is composed of three interconnected residences surrounding a central patio. The architecture blends French academic and Bourbon styles, featuring classical elements, Art Nouveau details, and a mansard roof. Inside, visitors can admire works by renowned Argentine and American artists such as Antonio Berni, Pablo Curatella Manes, and Roberto Matta. The palace also houses a valuable collection of pre-Columbian art and a library specializing in international law and relations. Guided tours are available, offering insights into the palace's history, architecture, and art collection. These tours provide a glimpse into the opulent lifestyle of the Anchorena family and the palace's role in Argentine diplomacy.
