The Muyil site was inhabited very early on by the Maya in the Yucatan Peninsula when people migrated from Petén Guatemala north to the fourth century AD. Found artifacts and pottery that dates have been dated to as far back as the year 350 BC and apparently remained inhabited until the years of 1200 - 1500 , or until shortly before the arrival of the Spanish conquistadors .
The ruins of Muyil are an example of the architecture of the Petén with some architectural resemblance to the ruins of Tikal in Guatemala . Its lake-proper location in the lagoon of Sian Ka'an - gave the place a strategic position on the trade route of the Maya along the coast and through a network of channels in this region, which is now part of the tourist area of the Mexican Caribbean . Among the goods traded along this route were the jade , the obsidian , the chocolate , the honey , feathers and of course the salt .
