Museum of Sydney, History museum in Bridge Street, Sydney, Australia.

The Museum of Sydney is a history museum on Bridge Street that combines archaeological finds, objects from different periods, and digital displays to tell how the city developed over time. The collection comes from excavations at multiple sites and documents both the early colonial period and the city's modern growth.

The site sits on the remains of the First Government House from 1788, the residence of the first governor and the starting point of European settlement in Australia. The museum building was constructed here much later to preserve the archaeological layers and their importance to Sydney's origins.

The name was contested: commissioned as the First Government House Museum, it was renamed in November 1993 while the building was still under construction, and the change drew protests. The site is also where Sydney's Aboriginal people first met British colonists, a contact the displays address alongside the colonial story.

The public entrance is via First Government House Place off Bridge Street, on the corner with Phillip Street. The forecourt is a public plaza where the outline of the first Government House is marked in inlaid stone, and glass display cases set into the pavement show excavated drains and privies in their original context.

Stone markers carved into the ground in front of the museum outline the exact shape and size of the original governor's house, helping visitors mentally reconstruct the first building on this site. These ground-level markers make the hidden history beneath the city tangible and leave a strong impression on many visitors.
