Begun in 1561 and completed 38 years later, St. Ildefonso is the oldest cathedral on the American continent (though an older one can be found in the Dominican Republic). It took several hundred Maya laborers, working with stones from the pyramids of the ravaged Mayan city, 36 years to complete it. Designed in the somber Renaissance style by an architect who had worked on the Escorial in Madrid, its facade is stark and unadorned, with gunnery slits instead of windows, and
faintly Moorish spires. Inside, the black Cristo de las Ampollas (Christ of the Blisters) occupies a side chapel to the left of the main altar. At 23 feet tall, it's the tallest Christ in Mexico inside a church. The statue is a replica of the original, which was destroyed during the revolution in 1910, which is also when the gold that typically decorated Mexican cathedrals was carried off. According to one of many legends, the Christ figure burned all night yet appeared the next morning unscathed—except that it was covered with the blisters for which it's named. You can hear the pipe organ play at the 11 am Sunday Mass.
