The interior contains some outstanding artwork, including an altarpiece by Sebastián Herrera and paintings by Claudio Coello, Herrera, and Ricci. The decor is baroque, there are numerous side chapels, barrel vaulting, and a huge dome. The façade features large built-in columns, a portico, and a vaulted niche containing sculptures by Juan Pascual de Mena. It's also known as the Colegiata de San Isidro, as it was part of a college founded by the Jesuits in the 16th Century. The remains of Madrid's patron saint, San Isidro, lie here.
