Dating back to around 100 AD, the capital of a powerful dynasty during the Mayan Classical period, ruling much of the surrounding area, is one of the Mayan world's greatest archaeological sites - and a UNESCO World Heritage Site - because though while it's far from the largest, it boasts a large number of sculptures and hieroglyphs, on temples, stelae, altars, and even the site’s single most important structure, the Hieroglyphic Stairway, Right alongside it, Copán Ruinas is a marvelous small town with lovely cobblestone streets, colorful buildings, abundant greenery, and hospitable Mayan locals.
