This catholic church is also known as the Church of the Mexicans and it is the work of the architects Enrique de la Mora y Palomar and José Ramón Azpiazu, and the engineers José Antonio Torroja and Félix Candela. It has an octagonal floor plan inscribed in a circumference of a diameter of 53.74 m.

It features a very characteristic roof that consists of eight 4 cm-thick hyperbolic paraboloids. The side closures are made up of folded plates combined with 2 cm stained-glass windows.  Four hollow central pillars support the roof and the lateral surfaces are also formed by paraboloids.

It is a processional church where the altar is situated in the center and the congregation spreads around the stairs that form an amphitheater. This leaves a wide aisle at the higher lever where people can move around comfortably.
