Iglesia Colegiata de San Isidro
Madrid's original cathedral
This monumental twin-towered church at the top of Calle Toledo was the city cathedral until the Catedral de la Almudena was completed in 1993.
Completed in 1664, it was originally the headquarters of the Jesuit Order in Spain until their expulsion in 1767.
The single nave is lined with elaborate chapels and features an impressive altarpiece and a fantastically ornate cupola.
It also houses the remains of the city's patron saint San Isidro and his wife Santa María de la Cabeza.
