Antigua Guatemala, commonly known as Antigua or La Antigua, is a city in the central highlands of Guatemala. It was the capital of the Captaincy General of Guatemala from 1543 through 1773, and its Baroque-influenced architecture and layout date from that period. This has earned it a UNESCO World Heritage Site designation in 1979. The population of the city was 65,000 in the 1770s, however, much of the population moved away in the late 18th century. By the 1990s, the city had only reached half of that number, and in 2007 the population was registered as 34,685.
