The Mayon Volcano in the Philippines has erupted numerous times, but the worst event took place on the 1st of February, 1814.
Many decades later (though the actual date is unknown) the 18th-century Franciscan Cagsawa church was still standing (though badly damaged). The ruins have since disintegrated significantly.
The disaster killed between 1200 and 2200 people, with different records stating wildly different numbers.
Since then, the volcano has erupted a number of times, including in July 1928, photographed above.
