Iglesia de San Cristóbal anchors one of Mérida's older neighbourhoods east of the centre, with a broad façade and a plaza that feels more residential than the cathedral square. It is a useful stop if you are walking beyond the tourist core and want to see how the city's historic churches structure local life.
The church is most rewarding in context: combine it with nearby markets, low arcades, and streets where colonial Mérida gives way to everyday Yucatecan routines. It is not as grand as the cathedral, but it helps make the city feel larger and more lived-in.
