Founded in New York in 1954 as the Spanish Institute by a group of Americans with a profound interest in Hispanic culture, the Institute’s mission is to stimulate interest in the United States in the culture, art, language, literature, history, and way of life of Spanish-speaking countries, while promoting mutual knowledge and understanding.
A particularly important chapter in its history is associated with 684 Park Avenue, the Oliver D. Filley House. In 1965, philanthropist Margaret Rockefeller Strong, Marquesa de Cuevas, saved the historic building from demolition and, together with the McMicking Foundation, donated it to the Institute. The building served as the Institute's headquarters for several decades and became an important venue for Spanish cultural life in New York, hosting exhibitions, lectures, performances, receptions, and other cultural programs.
In 2003, Her Majesty Queen Sofía of Spain accepted the Board of Directors’ unanimous decision to rename the organization in Her Majesty’s honor. As the Institute’s Patroness of Honor, Queen Sofía has maintained an active relationship with its mission and activities.
In 2014, the building at 684 Park Avenue was sold. Today, the QSSI continues its work through educational and cultural initiatives in history, art, literature, performing arts, science, and other fields, collaborating with institutions throughout the United States, Spain, and the wider Spanish-speaking world thus deepening mutual understanding and creating bonds of peace.
