The "Palacio San Martin" can be found on the Avenida Arenales 761, in Retiro, just in front of the Plaza San Martin. It was previously known as the Palacio Anchorena. It was built between the years 1905 and 1909, by architect Alejandro Christophersen, under the auspices of Mercedes Castellanos de Anchorena (the family was also involved in the story of a previous post El Kavanagh). Today, the building is the venue of the Protocol wing of the Chancellery, depending on the Ministry of Foreign Affairs. Between the years 1936 and 1993 it was the actual venue of the Ministry of Foreign Affairs, until the modern building of the chancellery was erected right in front of it.
