ECAP excavations along the erosion cut of the Copan Acropolis. Tunnel excavations penetrated the massive layers of royal architecture built during the Early Classic period from ca. 400-650 AD.Copan was the capital of a large and prosperous kingdom from 426 to 822 CE, during the Classic period of Maya civilization. Located in western Honduras, Copan is a UNESCO World Heritage Site that attracts visitors from all over the world. Array of pottery vessels placed in the tomb of Copan’s 8th ruler, Wil Ohl K’inich, excavated beneath the Jaguar Stairway of the Acropolis East Court.From 1989 to 2003 the Early Copan Acropolis Program (ECAP) of the Penn Museum conducted excavations at Copan to document the origins and architectural history of the Acropolis, the famous royal center of the site, and to correlate these findings with Copan’s dynastic history. Working with the Instituto Hondureño de Antropología e Historia, ECAP excavated some 3 kms of tunnels beneath the Acropolis uncovering architecture, inscriptions, and tombs dating to 400-600 CE.

The Copan Acropolis excavations provide the most thoroughly-documented and unique body of information on the origins of a Classic Maya kingdom ever assembled. ECAP’s research has fundamentally enhanced our knowledge of the development of Maya states thorough the discovery of several new Early Classic hieroglyphic texts, a sequence of well-preserved funerary temples, the tomb and royal residence of the founder of the Copan dynasty (K’inich Yax K’uk’ Mo’, reigned 426-437), the elaborate tomb of a royal lady (most likely the Founder’s Queen, name unknown), and the tomb of Copan’s 8th king (Wil Ohl K’inich, reigned 534-551). Of special importance was the discovery and documentation of Copan’s earliest royal palaces that provides some of the most crucial evidence for the origins of the Copan state and its sociopolitical organization.
