The Great Plaza at Copán is lined with 21 standing stone stelae — portrait monuments to the kings of the Copán dynasty, each carved with the ruler's image and surrounded by hieroglyphic text recording their names, dates, and ritual events. The stelae are the finest examples of Classic Maya sculpture anywhere: the figures are deeply carved in near-full relief, with elaborate headdresses, jade jewellery, and ceremonial regalia rendered in extraordinary detail.
Each stela was carved from a single block of greenish trachyte quarried locally, often weighing several tonnes. Most were erected between approximately AD 600 and 800, during the reigns of Copán's most powerful kings. Altar stones at the base of many stelae were used for ceremonial offerings. The stelae are numbered and described in the site guidebook available at the entrance; picking out key details — the double-headed serpent bar, the corn god imagery, the jaguar skins — is one of the pleasures of a careful visit.
