 Parliament House is significant for its association with important social and political figures of the nineteenth and twentieth centuries

The Parliamentary precincts comprise the original old colonial Georgian building known as the Rum Hospital, which was finished in 1816 as well as later additions and extensions to the Parliament buildings.A new chamber was constructed at the northern end of the building in 1842 to accommodate the partly elected and partly nominee Council which was established with the new constitution of 1842.The Legislative Council is a pre-fabricated cast-iron building, initially shipped to Melbourne from Glasgow, Scotland, before being sent to Sydney as one of the two parliamentary chambers and is still a seat of government in NSW today.
