The Church of San Sebastián, founded in the 16th century, was built to serve the spiritual needs of Antigua Guatemala’s peripheral neighborhoods. Dedicated to Saint Sebastian, protector against disease, it became a key site for religious celebrations. Its modest Baroque design includes thick masonry walls built to withstand earthquakes. Damaged by the 1717 and 1773 earthquakes, it fell into partial neglect after the capital’s relocation. Restoration efforts in the 20th century helped.
