Built atop two 16th-century monasteries—both turned to rumble from earthquakes—the enduring 18th-century La Merced Church is a marvel of ingenious design. Inside, admire the arabesque-patterned stucco and the dazzling gold-leaf retable behind the altar. Then climb into the bell towers for a bird’s-eye view of the UNESCO World Heritage–listed city.
Visit the church as part of a walking tour of Antigua to discover the city’s colorful Spanish baroque architecture, and top attractions such as Casa del Jade and a working coffee plantation. End the day atop Cero de la Cruz or with a dip in hot springs heated by Pacaya, the most active volcano in Guatemala.
