Overview
- The Proyecto Templo Mayor and INAH presented findings that offerings 186, 187 and 189 together likely constitute the largest ritual deposit attributed to Moctezuma I.
- The three tepetlacalli contain 43 Mezcala‑style green‑stone pieces, with 15 in offering 186, 15 in 187 and 13 in 189.
- Researchers identified shells and other mollusk remains from Pacific coasts, reinforcing Tláloc‑related themes of rain, fertility and maritime abundance.
- Accessing the deposits required lifting monumental serpent sculptures weighing roughly 600 to 1,000 kilograms using ropes, levers and wooden rollers.
- Conservators stabilized red and white pigments with controlled humidity and natural fixatives over six to eight months, after which the materials enter museum care for further study.
