The Historical Organs of the Clérigos continue to function perfectly, despite being more than 200 years old.
They were made by the Spanish Dom Sebastião de Acunha and, like the building in which they are inserted, are a notable example of the Baroque style that characterized the late eighteenth century. The box of the organ on the side of the epistle is surmounted by a moon; the side of the gospel is characterized by a sun. The unification of these two elements refers to the idea of absolute and totality.
In 2015, these organs were played daily, always at the same time (at noon), often with the two historical organs simultaneously and sometimes with the participation of singers. These free concerts enchant the Porto residents and tourists and are another attraction for an already much sought after destination as well as being appreciated by those who visit the city.
In December 2017 Organ Concert # 1000 was celebrated. It was a special day, where two organists and a soprano were in attendance. But every day one can celebrate the long life of these historical pipe organs and enjoy their music.
