It is also known as Chunyaxché.
Muyil was inhabited since 350 BC by the Mayans in the Yucatan Peninsula when a Guatemaltecan Peten group migrated towards the north and apparently the place remained inhabited until 1200-1500, shortly before the arrival of the Spanish conquistadors.
The ruins of Muyil are an example of the architecture of the Petén with some architectural similarity to the vestiges of Tikal in Guatemala. Its lakeside location in the lagoon of Sian Ka'an, gave to the place a strategic position on the trade route of the Mayans along the coast and through a network of channels in this region, which is now part of the tourist resort in the Mexican Caribbean.
Among the goods traded along this route there were jade, obsidian, chocolate, honey, feathers and of course salt.
It is estimated that one of the major cities that used this trade and possibly regionally controlled the commercial traffic was Coba (at about 40 km to the northwest) with which Muyil had l important links.
