GARDENERS have uncovered a hidden brick structure at Lanyon Homestead believed to date back to the 1800s.

The find, a 2mx2m brick vault that resembers the side of a submerged cyclinder on its side, was discovered last week by gardeners while removing a large mass of ivy. The origins of the structure are still unknown.

Director of ACT Museums and Galleries Shane Breynard said speculation is rampant among Lanyon staff as to the purpose
of the structure with rumors rife that it may have been a grain or food store, an early septic tank, a water reservoir or even an early bushfire shelter.

According to Lanyon Homestead, the bricks and mortar used appear to be sourced locally and resemble other brickwork on the site dating from the 1800s. The structure also shows signs of whitewashing in the past.

Historic Places major project senior manager, John Armes is currently researching the purpose of the structure and is looking for any early photographs of the garden where the brick vault was found.

Anyone with information is encouraged to contact John by email, john.armes@act.gov.au

Lanyon Homestead is an ACT Government facility located 10 minutes south of the Tuggeranong Town Centre on Tharwa Drive.
