This room displays pieces from various underwater archaeological contexts submerged in continental waters, linked to the Maya culture, which materially evidence the connection between divine concepts, such as water, the womb of the earth, and the underworld as a sacred space of death, life, and rebirth. Key finds come from underwater archaeological sites in the cenote San Manuel, Tizimín municipality, and cenotes in Homún and Chemax, Yucatán. These sacred spaces revealed "chocolatera" jars from the Late Preclassic period (400 BC to 200 AD), similar to those found in terrestrial sites in Belize and Guatemala, associated with burials or mortuary deposits.
