Bilbao is a Mesoamerican archaeological site about 1 mile (1.6 km) from the modern town of Santa Lucía Cotzumalguapa in the Escuintla department of Guatemala.[2] The site lies among sugar plantations on the Pacific coastal plain and its principal phase of occupation is dated to the Classic Period.[3] Bilbao was a major centre belonging to the Cotzumalhuapa culture with its main occupation dating to the Late Classic (c. AD 600–800).[4] Bilbao is the former name of the plantation on which the site lies and from which it has derived its name.[5]
