Mexico City Metropolitan Cathedral

"Mexico City’s mammoth cathedral was built across three centuries (1573–1813)—starting soon after Cortés and his allies vanquished the Aztec Empire—using stones taken from a destroyed indigenous temple. Today’s sanctuary serves up contrasts between unadorned neoclassical walls alongside exuberant gilt chapels and altarpieces as well as a massive pipe organ, with some baroque elements, that’s still dusted off and played from time to time. Be sure not to miss the high altar, and consider shelling out for a visit to the sacristy, with its glistening dome, grand canvases, and massive cabinets, fit to hold an archbishop’s entire stock of holy utensils. And for a queasy view of how much the ground beneath the city is sinking, note how chandeliers appear to list in comparison to the chapel’s vertical lines."
