A three-year project is underway to discover more about the prehistoric landscape close to La Hougue Bie.
Visiting experts from England, Wales, Sweden, and Denmark are working in the field opposite the entrance to the tomb over the next two weeks.
The dig is part of a project carried out in partnership with Jersey Heritage, which owns the field known as Jardin de Perchard, and in coordination with Société Jersiase, whose members are joining the dig.
The team is aiming to reconstruct the story of this landscape spanning the deep Ice Age, later prehistory, and more recent times.
Olga Finch, Jersey Heritage's Curator of Archaeology, said:
"The start of this three-year project marks the beginning of an exciting new chapter of archaeological discovery for Jersey.
"The archaeologists hope to understand how the landscape was used 6,000 years ago at the time the La Hougue Bie burial chamber was being used and what the deep buried records of Ice Age sediment beneath the field can reveal about climate change and ancient people, including Neanderthals, during the last quarter of a million years."
The dig runs until Thursday 6 August and will resume over the following two summers.
Dr Matt Pope, from the UCL Institute of Archaeology, said:
"We know a fair amount about the prehistory of Jersey’s coastline, but the interior of the Island is now starting to be taken seriously by archaeologists.
"This project will help to unlock Jersey’s full story, test scientific methods of investigation and explore the neighbourhood of one of Europe’s most spectacular prehistoric monuments, La Hougue Bie.
"Research of this kind also strengthens our understanding of the remarkable Ice Age landscapes that lie at the heart of Jersey’s aspirations to become a UNESCO Global Geopark."
Visitors over the next two weeks will be able to see the dig and watch the archaeologists at work from the top of the mound by the chapel.
A free open day is being held in the field on Sunday 2 August from 10am to 2:30pm.
