The Luminous Lagoon stretches across the Trelawny marshlands from the little community of Rock to the town of Falmouth. In the 18th century, when sugar was king, Falmouth was one of Jamaica's most important ports.

At the convergence of the Martha Brae River and the Caribbean Sea, the lagoon housed a dock where large ships from England unloaded cargo onto smaller ships for delivery further up the river. After reloading with sugar, rum, and other Jamaican goods, these boats would return to the harbour.

Scientists discovered that the lagoon's location was essential for another reason years after the sugar trade stopped out.

The ancient Rose Hall Great House, a restored 18th-century architectural marvel, sits at the centre of the site. Golf course frontage and spectacular views of the Caribbean Sea can be found in nearby luxury home complexes. Rose Hall is home to two of the Caribbean's most well-known golf courses, with 54 holes designed by Rick Baril and Robert von Hagge.
