San Juan Parangaricutiro Buried Church

The ruins at San Juan Parangaricutiro mark the location of a town of 1,895 people that was progressively buried by lava from the Paricutín volcano, which began erupting from a cornfield on 20 February 1943 in one of the few documented cases in recorded history of a volcano's birth being observed from its very first hours. Over the following months the eruption produced substantial ash fall and slow-moving lava flows that advanced across the surrounding farmland, and by August 1943 the flows had reached and engulfed most of the town, forcing a gradual evacuation that unfolded over weeks rather than in sudden crisis, since the lava's advance was slow enough to allow residents to relocate along with, in some cases, salvaged building materials and religious items. The town's main church was the largest structure in San Juan Parangaricutiro, and while its lower walls and most of its structure were consumed by the advancing lava, the upper portions of the apse, bell tower remnants and altar area remained above the solidified flow, creating the partially buried ruin that stands today surrounded by a black lava field that has since developed some vegetation cover. The exposed altar continues to function as an active site of devotion: it is tended with candles, flowers and offerings by pilgrims and by descendants of the original town's residents, many of whom relocated to found the new town of San Juan Nuevo Parangaricutiro nearby. The eruption itself continued intermittently until 1952, ultimately building the Paricutín cinder cone to a height of over 400 metres above the original farmland, and the buried church remains one of the clearest single images of the eruption's destructive reach, visited both as a geological curiosity and as a place of ongoing religious significance.
