The Magistral Cathedral of Saint Justus and Saint Pastor (Spanish: Catedral de los Santos Niños Justo y Pastor) is a Roman Catholic cathedral located in Alcalá de Henares, Spain.

Together with Saint Peter's of Leuven, they are the only churches worldwide to hold the title of Magistral, as their canons are required to be doctors in Theology.

They emphasize the cover of the western facade of Flamboyant Gothic style, in which central medallion depicted on Saint Ildefonso; and the tower, designed by Rodrigo Gil de Hontañón[6] and Rodrigo Argüello, in herrerian style, with a height of 62.05 meters.

The building's interior is divided into three naves covered by cross vaults resting on pillars fasciculados.

The entire building suffered much in that fire, and countless works of art and objects of great historical, devotional and sentimental value were lost.
