The Temple of Caballero de Gracia is a Madrid church built in the neoclassical style. The building itself is very simple - the interior is actually a huge hall, in which only the choir, transept and presbytery indicate the religious purpose of this place. The oval dome with skylights and properly arranged windows make the church known for the effect of light gradation and many visual effects.
The architect of the temple was Juan de Villanueva, who prepared 17 building designs in 1782. Villanueva studied in Rome, and after returning to Spain he became the official architect of the monarchy. He designed, among others Astronomical Observatory and the building where the Prado Museum is currently located. Work on the described church was a milestone in his career, the first important religious work.
