Pacbitum - Means "Stones Set in the Earth" in Mayan. It is located just two miles to the east of San Antonio on private land and is the most southern of the Belize River sites. Archaeological evidence shows Pacbitum to be one of the oldest Preclassic Mayan sites. The site contains nearly 30 constructions of temples and pyramids and several stalae. One of the interesting part of the ruins at Pacbitum is an irrigation system which was built above the ground. The ruins have also produced precious Mayan art and rare musical instruments have also been found.
