The Colegio San José Auditorium in Buenos Aires, nicknamed “El Coloncito” for its resemblance to the Colón Theater, is one of those architectural treasures that surprise even those who think they know the city well. Inaugurated in 1915, it is part of a building declared a National Historic Monument and, for more than a century, has hosted academic and cultural events. However, the Colegio San José Theater remains one of the least known spaces in Buenos Aires, a secret that deserves to be discovered.
What makes the Colegio San José Auditorium unique
With its Doric columns in the stalls, Ionic style galleries and Corinthian details in the ceiling, the Auditorio Colegio San José impresses anyone who crosses its doors. Its 36 meters long and 14 meters high make it an imposing space for a school, something that in the 60’s and 70’s was taken advantage of when the hall was transformed into a movie theater for students on weekends.
Over the years it has hosted everything from musical evenings to the Argentine Harry Potter convention, which chose it for its resemblance to Hogwarts . On the same stage, a marble inscription with the Latin phrase Cor unum et anima una (“One heart and one soul”) reflects the school’s identity and values.
What you can do at the Colegio San José Auditorium
The Colegio San José Auditorium opens its doors for occasional cultural activities, such as concerts, conferences and special presentations that take advantage of its acoustics and historical character. Among them, Candlelight in Buenos Aires, the candlelight concert series that brings classical music and tributes to unique venues in the city, stands out.
