For 14 months, a team of more than 80 engineers, surveyors, restorers, architects and archaeologists have been toiling to protect part of one of Mexico's most important and ancient sites, the Templo Mayor complex - which the Aztecs believed to be the center of the universe.
A roof that covered the House of Eagles, part of this 500-year-old site, collapsed in a storm last April under the weight of hail and rain. It caused only minor damage, but left the team scrambling to protect the site in the center of downtown Mexico City's historic district.
