Iron Age human remains unearthed
Iron Age human remains have been unearthed during the construction of a new school.
Burials of children and animals discovered at the site are believed to be more than 2,000-years-old.
Archaeologists have traced numerous finds, in Carshalton, south-west London, to the Iron Age and Roman era.
Experts, who said it was one of the most important finds in the capital in recent years, believe the area was once a small farming community made up of earth and timber roundhouses with thatched roofs.
The discoveries were made by workmen laying the foundations for the new Stanley Park High School on the former site of Queen Mary's Hospital.
Graham Tope, from Sutton Council, said: "We are very excited to find such important examples of early life in Britain.
"Archaeologists tell us these excavations are certainly the most important ever undertaken in the London Borough of Sutton and very important in the context of Greater London where much of other evidence of these periods has been destroyed by earlier development."
The site lies less than 100m from one of the largest late Bronze Age hilltop enclosures in south-east England, discovered during the construction of a hospital in the early 20th century.
Iron Age features, including a possible livestock pathway, shallow gullies and pits have also been identified.
The school intends to share the discoveries with the pupils to be used for inspiration in history lessons, the authority said.
