The Royal Basilica of Saint Francis the Great (Spanish: Real Basílica de San Francisco el Grande) is a Roman Catholic church in central Madrid, Spain, located in the neighborhood of Palacio.

The temple once functioned as the National pantheon and enshrined the remains of famous artists and politicians.

It is reportedly the fourth biggest dome in Europe after the Pantheon, St. Peter's Basilica and the Florence cathedral.

[4] Although they are derelict and unringable, the church holds the only peal of change ringing bells in Spain, cast by John Warner and Sons in 1882 and weighing around 430 kg (950 lb).
