On April 9, 1925, the Pontevedra Polyphonic Choral Society performed publicly for the first time in the Church of San Francisco. It was founded by a group of prominent Galician figures, including Antón Losada Diéguez, Alfonso Rodríguez Castelao, Antonio Blanco Porto, Antonio Iglesias Vilarelle, and later Alexandre Bóveda. Therefore, its centenary will be commemorated in 2025.
Since that date, more than 700 concerts have been performed, including those in Lisbon in 1934, Buenos Aires, and Montevideo in 1979. Concerts have also been held on the island of Tenerife, from July 1 to 6, 1985; in Paris in 1991; and in other French cities (Tours, Mettray, and Angersen) in 1998. In Andorra in 2000. In December 2018, at the Gaiás Museum of the City of Culture in Santiago de Compostela, and in 2019, on Madeira Island, it participated in the 22nd Festival of Christmas in Funchal. In 2023, it performed the Cantigas of Martín Códax in Pontevedra and Santiago, in the year dedicated to the Galician troubadour by the Royal Academy of Fine Arts of Galicia.
Since its founding, the Choir has dedicated itself to performing medieval music, 16th and 17th-century polyphony, primarily sacred music and madrigals, and Galician popular music.
In its 100 years of existence, the Choir has been conducted by Antonio Blanco Porto and Antonio Iglesias Vilarelle, among others, and since 2013 by Nanette Sánchez Ordaz. In 1951, it was conducted by Leopoldo Stokowski at the Cathedral of Santiago de Compostela in a concert of works by Tomás Luis de Victoria.
The awards received included the First Silver Medal from the City of Pontevedra, the City of Pontevedra Award in 2000, and the 1975 award from the Friends of Pontevedra Association.
