The major themes associated with the history of the study area are entertainment, transport, the Sydney Harbour Bridge and in later years development pressure and suspected corruption. From the mid 1930s the history of the area is predominated by the history of Luna Park - an institution with which many Sydneysiders and visitors have had some association. The distinctive artwork and architecture of Luna Park, like that of the Opera House and the Harbour Bridge, have helped create a cultural icon linked by juxtaposition with the aforesaid institutions.
