Seen for the first time in centuries, a 1,500-year-old tomb comes to light via a tiny camera lowered into a Maya pyramid at Mexico‘s Palenque archaeological site in April. The intact, blood-red funeral chamber offers insight into the ancient city’s early history, experts say.
The tomb was discovered in 1999, though researchers have been unable to get inside due to the precarious structural state of the pyramid above. Any effort to penetrate the tomb could damage the contents within, according to the team, which is affiliated with Mexico’s National Institute of Anthropology and History.
Instead, the archaeologists lowered the 1.6-by-2.4-inch (4-by-6-centimeter) camera through a 6-inch-wide (15-centimeter-wide) hole in an upper floor of the pyramid.
