The Metropolitan Cathedral of Monterrey dominates the northern end of the Gran Plaza, its twin towers rising above the city centre. The exterior is plain Baroque, with a facade of pale stone that is severe by Mexican standards. The interior is more ornate, with a gilded altarpiece and painted ceilings that reflect the cathedral's long construction history.
It is an active cathedral and religious services take place throughout the day. For a building of this significance, it is relatively undiscovered by visitors who tend to head directly to MARCO or the Macroplaza.
