I already saw a Travel Agency advertising Antigua and Barbuda with a photo of Antigua Guatemala...

Built 1,530.17 m above sea level in an earthquake-prone region, Antigua Guatemala, the capital of the Captaincy-General of Guatemala, was founded in 1524 as Santiago de Guatemala. It was subsequently destroyed by fire caused by an uprising of the indigenous population, re-established in 1527 and entirely buried as a result of earthquakes and an avalanche in 1541. The third location, in the Valley of Panchoy or Pacán, was inaugurated in March 1543 and served for 230 years. It survived natural disasters of floods, volcanic eruptions and other serious tremors until 1773 when the Santa Marta earthquakes destroyed much of the town. At this point, authorities ordered the relocation of the capital to a safer location region, which became Guatemala City, the county’s modern capital. Some residents stayed behind in the original town, however, which became referred to as “La Antigua Guatemala”. - in: http://whc.unesco.org/en/list/65
