On Plaza Grande's southwest side stands Quito’s cathedral. Although not the most ornate of the old town’s churches, it has some fascinating religious works from artists of the Quito School. You’ll also see the ornate tomb of Mariscal Sucre, the leading figure of Quito’s independence. And behind the main altar is a plaque marking where President Gabriel García Moreno died on August 6, 1875; after being slashed with a machete outside the Palacio del Gobierno, he was carried, dying, to the cathedral.

Don’t miss the painting of the Last Supper, with Christ and disciples feasting on cuy asado (roast guinea pig), chicha (a fermented corn drink) and humitas (similar to tamales). The Nativity painting includes a llama and a horse peering over the newborn Jesus. Admission includes a free guided tour in Spanish.
