The Copán ruins are an ancient Mayan site, discovered in 1570 by Diego García de Palacio. This area was deeply important as a political, civil and religious center of the Copan Valley. The city was occupied by the Maya for around 2,000 years, and it was abandoned in the 10th century. It’s now a Unesco World Heritage site, and you can wander at will through the vast area and learn about the history of the ancient civilization. Explore the Maya citadel, where you’ll see portrait-style stone monuments called stelae, overlapping step-pyramids, and many ruined buildings.
