Laguna de Bacalar and its limestone basin

The lagoon sits in south-eastern Mexico on the Yucatán Peninsula, where porous limestone and underground water are part of the landscape. Its elongated form and broad bands of blue make the water body easy to read from the edge of town.elongated form

Laguna de Bacalar is linked to cenotes and groundwater, and its floor includes limestone and shallow sand. The name of Bacalar belongs to the town on the western shore, which sits directly beside the lagoon.western shore

Stromatolites, cenotes and clear water

The lagoon is known for stromatolites and other microbial structures in shallow water. These layered formations sit on the lagoon floor and along its margins, tying the place to living limestone as much as to open water.stromatolites

Cenotes connect the lagoon to the karst beneath the peninsula, and the water keeps a clear, freshwater character. That mix of surface colour and submerged limestone gives the lagoon its most recognisable view from Bacalar’s shore.karst beneath

San Felipe and Bacalar’s colonial edge

Laguna de Bacalar is part of Bacalar’s historical setting, and the town’s fortified edge remains tied to the lagoon. The Fuerte de San Felipe de Bacalar belongs to the eighteenth century and reflects the colonial period of the town.

Antonio de Figueroa y Silva ordered the fortification, and Juan Podio is named in connection with its design. The fort’s later life as a museum adds a built, human counterpoint to the lagoon’s natural shoreline.Antonio de Figueroa y Silva
