You never forget your entrance into this place. It's set in the jungle. Not just the ruins, but the bustling town and its slick, dangerous mountain road from San Cristobal. In the early spring, the water drips everywhere; the walls sweat as the clouds leak. It's a muddy, messy place, but with buildings and histories to kill for. One of the most violent cities in human history, the blood and broken bones of the Mayan people still seem to cling to the rocky surfaces jutting from the jungles. Not that easy to get to, despite its popularity. Many of these pictures were taken by Martina Jacova while she co-produced Blue's "Burn & Scar."
