The Conservatorium Site contained historical archaeology dating from c1800 into the twentieth century. The main archaeological evidence at the site relates to the Government Stables (1817-1821) which forms the core of the Sydney Conservatorium of Music buildings. The Stables archaeology includes the southern forecourt with its road and drainage system, a cistern, artefacts from a large rubbish dump (c1840-1913), and surviving remains of the Stables internal configuration hidden by twentieth-century alterations. Remains of an early bakehouse (c1800-1813) survive underneath Verbrugghen Hall which was built within the stables courtyard.
This project retained archaeological remains which visitors can see in the entrance foyer and downstairs. There are display cases downstairs with artefacts recovered during the archaeological program as well as sections of one of the large drains. Other aspects of the sites archaeology and history are found within the Stables building.
