Old Ambulance Station, Heritage ambulance station in The Rocks, Australia.

The Old Ambulance Station at 73 George Street is a two-storey masonry building with a cellar and a 1928 facade by Howie Moffot & Co., described as Georgian Art Nouveau. Its single pitched gable roof of corrugated iron is screened from the street by parapets, and the first-floor ceilings are pressed metal. The rear yard is enclosed by a sandstone boundary wall.

Matthias Hooper built the three-storey Kings Head public house here in 1842–43; it was renamed the Great Pacific Hotel in 1874 and the P&O Hotel in 1885. After the government resumed the property in 1900, Howie Moffot & Co. designed a new facade in 1927–28, and the Circular Quay Depot of the Central District Ambulance Service opened in 1928. The ambulance service left in 1990, and the Ken Duncan Gallery occupied the building from 2008 to 2018.

The building's name changed with its licensees: the Kings Head became the Great Pacific Hotel in 1874, then the P&O Hotel in 1885 under licensee Mary A. Ferguson. From 1911 to 1927 the Salvation Army ran a Naval and Military Home here. Look for the 1928 facade by Howie Moffot & Co.

The building functions as a private commercial space with limited public access to the interior. A walk through The Rocks provides good opportunities to view its exterior architecture and distinctive facade details.

The building features original sandstone boundary walls and brick structures that reveal the neighborhood's architectural evolution through different eras. These preserved elements tell the story of how The Rocks transformed over nearly two centuries.
