The Templo Expiatorio is Guadalajara's most ambitious piece of ecclesiastical architecture — a neo-Gothic church that took 75 years to build, from 1897 to 1972, with work repeatedly interrupted by the Mexican Revolution, political unrest, and funding crises. The result is a building that feels genuinely medieval in its ambition, with soaring pointed arches, flying buttresses, and an interior entirely lined in coloured glass.
The main attraction beyond the architecture is the clock tower, which features a mechanical parade of twelve apostle figures that rotate past an opening every hour. The detailed stonework on the facade — carved from cantera stone — rewards close inspection. The church stands near Parque Revolución in the Colonia Americana neighbourhood, one of the better parts of the city for wandering.
