Fernández Anchorena Palace

The Fernández Anchorena Palace is an architecturally significant former residence in the Recoleta section of Buenos Aires, Argentina.

The mansion was commissioned by Juan Antonio Fernández and his wife, Rosa de Anchorena, to Eduardo Le Monnier (1873 – 1931), a French Argentine architect.

Designed in 1907 in the Second Empire style favored among Argentine high society at the time, the palace was completed in 1909, though the couple never inhabited the Alvear Avenue landmark.

The founder of the Catholic Ladies' League and financier of a working women's assistance fund, a number of churches and a hospital pavilion bequeathed the residence to the Holy See, in 1947.

Upon her death in 1949, it became the Apostolic Nunciature in Argentina; the Pope at the time, Pius XII, had been a guest of hers (as Cardinal Pacelli) for his stay in Buenos Aires on occasion of the Eucharistic Congress held in 1934.
