San Clemente is a ruin of the ancient Maya civilization in Guatemala. Its main period of occupation dates to the Classic period of Mesoamerican chronology (approximately 250 – 950 AD). The ruins were first described in the late 19th century, before being visited by a number of investigators in the early part of the 20th century.
