Earthquake of 1773
The Earthquake of 1773, historically known as the Santa Marta earthquakes, was a series of catastrophic seismic events that almost completely leveled Santiago de los Caballeros (now Antigua Guatemala), then the capital of the Captaincy General of Guatemala. The most destructive tremors occurred on July 29, 1773, causing the collapse of grand churches, monasteries, and administrative buildings. Due to the extent of the damage and the perceived threat of future disasters, the Spanish Crown, urged by Captain General Martín de Mayorga, ordered the relocation of the capital to a safer location. This decision led to the 1776 founding of La Nueva Guatemala de la Asunción in the Ermita Valley, which is modern-day Guatemala City. In Antigua, the skeletal ruins remained as silent witnesses to the tragedy, giving the city its distinctive historical atmosphere. The event not only shifted the center of power but also ended Antigua's golden age as the political heart of Central America.
