A number of graves nearly 200-years-old have been discovered by construction workers under one of Sydney's busiest train stations.
Archeologists confirmed the discovery of a vault beneath redevelopment work for Central Station's two new metro platforms.
The vault constructed 181 years ago contains 11 graves from as early as 1840, according to inscribed metal plates.
While the vault mightn't contain any Indiana Jones-style relics, historians believe the discovery could provide some valuable insight into the city's colonial history.
Excavation director Dr Iain Stuart and his team are searching for the descendants of two people who are named on the metal plates - the Ham and the Perry families.

'The Ham family were quite well known in literary circles in Sydney and Victoria,' Dr Stuart said.
'These things seem far in the past, but we're talking to people who are really are very close to them, we're talking to people who are great grandchildren of them.'
The find is the second vault discovered under the construction site in which legible nameplates were found.
In 2019, workers unearthed a 161-year-old grave nearby sparking a hunt to find the man's living relatives.
That grave belonged to Joseph Thompson, who died in 1858 aged 80.
Mr Thompson was a draper by trade, who was born in England in 1779 before making his way to Australia.
He had 14 children and was a member of Pitt Street Congregational Church.

Where Central Station is situated was once the site of the Devonshire Street cemetery which was closed in 1867.
When the train station was built about 30,000 graves were relocated but records were not as well kept then and a number of unrecorded graves have since been unearthed in the redevelopment works.
More than 60 graves and five vaults have been discovered since the construction began in early 2019.

Central Station is undergoing a major upgrade that will see two new metro platforms built 27 metres underground.
The project will also deliver Central Walk - a new 80-metre long underground concourse connecting platforms.
This part of the project will open in 2022 while construction continues on the Sydney Metro - expected to be completed in 2024 - that will connect rail services between Bankstown and Chatswood.
