This is one of the strangest sculptures that I have ever seen and may be an interpretation of lost technology. Discovered at El Baúl, a Pre-Columbian archaeological site in Guatemala, and part of the Cotzumalhuapa Archaeological sites Zone, the unknown monument appears to weigh several tons and is partially buried in the ground.
Two small figures are carved into what can only be construed as a machine of some kind and pear out. There are symbols surrounding the figures which hold some unknown meaning. -Cliff — Details of Unknown Monument from El Baul (5 photos)
