ARCHAEOLOGISTS excavating a historic site have discovered the remains of a building thought to date back to around 1750.

Volunteers from the Orpington and District Archaeological Society joined the excavations at The Priory Gardens and Museum.

The dig in Church Hill, Orpington, unearthed the remains of the outer wall of what is thought to be a farm building.

Shards of Roman pottery, a milk bottle dating back to the 1930s and 100-year-old lead fruit tree labels were also found during the dig.

The museum is now looking at the possibility of digging more test trenches on the site.

Curator Adrian Green said: "This is just the tip of the iceberg.

"There may be lots of other remains waiting to be found."

The excavated items are being displayed in the museum's History of the Priory exhibition, which runs until September 24.
