How many times have you walked down 25 de Mayo Street in downtown Buenos Aires without realizing that hidden among those office buildings lies the oldest non-Catholic church in South America? It’s the Anglican Cathedral of St. John the Baptist, and this week you can explore it from the inside, as it will serve as the venue for a live performance by the New York Children’s Choir on June 30 at 7 p.m. Admission is free!
This 1831 Anglican church opens its doors for a free international concert: the neoclassical gem with the best acoustics in Buenos Aires
Buenos Aires is home to the oldest non-Catholic church in South America, and that’s just one of the many interesting facts about this Anglican cathedral. In fact, it exists because in 1825 Argentina signed a treaty of friendship and trade with Great Britain that granted, for the first time, religious freedom to British immigrants arriving in the country. Thus, this church was founded in 1830, and the land on which it stands was, in fact, a donation from Juan Manuel de Rosas.
A neoclassical gem with the best acoustics in Buenos Aires
The Anglican Cathedral of Buenos Aires was designed by Scottish architect Richard Adams and is a masterpiece of Neoclassicism, featuring six Roman Doric columns on its façade. In fact, if you walk by, you’ll recognize it because it looks like a small Roman temple amid modern buildings. It features stained-glass windows paying tribute to pioneering families of the British community and an interior style that gradually evolved into the Victorian style.

But its greatest secret lies in its acoustics because, unlike the traditional domes found in churches, this neoclassical church has a completely flat ceiling, which creates a sound-reflecting effect that gives any concert some of the most perfect acoustics in Buenos Aires.
In this secret and perfect corner of Buenos Aires, you’ll be able to enjoy the New York Children’s Choir.
