Anglican Cathedral of St. John the Baptist, Anglican cathedral in Buenos Aires, Argentina

The Anglican Cathedral of St. John the Baptist is a neoclassical building in Buenos Aires with a facade dominated by a portico of six Doric columns raised on a stepped platform. Its interior has Victorian stained glass windows, an organ, and walls adorned with memorials. A chancel and choir stalls were added in the 19th century, and the bishop's throne in the 20th.

Built in 1831, the cathedral stands as the first non-Catholic religious structure in Latin America, made possible by an 1825 treaty between Argentina and the United Kingdom. This construction marked a turning point for religious diversity in a predominantly Catholic region.

The cathedral hosts services in both English and Spanish, embodying the connection between British and Argentine communities that has shaped its identity. Visitors witness how this space bridges two cultural traditions through its daily religious practices.

The cathedral sits near Plaza de Mayo, about three blocks north of the Casa Rosada in central Buenos Aires. Regular services take place, so visitors should be mindful of worship times when planning their visit to explore the interior.

The cathedral's documentary archive has been held at the Max von Buch Library of the Universidad de San Andrés since 2007, where it is open for consultation. The building also keeps a Victorian-era organ and memorial plaques to British residents of Buenos Aires.
