Palacio San Martin
Beaux Arts palace built as three joined mansions for one aristocratic family, now a foreign ministry showpiece.
This guide to the Palacio San Martín in Buenos Aires traces a rivalry between two families across a single plaza. Mercedes Castellanos de Anchorena, matriarch of one of Argentina's richest dynasties, had architect Alejandro Christophersen join three mansions behind one Beaux Arts facade so her relatives could live side by side, finished by 1909 facing a church the family had built as their own tomb. Corina Kavanagh, new money the Anchorenas refused to accept, enters the story next, and family legend blames a forbidden romance with one of Mercedes's sons for what she did after. Look toward the alley beside the palace, which still carries her name.
