The Powerhouse Museum is the major branch of the Museum of Applied Arts & Sciences (MAAS) in Sydney. Although often described as a science museum, the Powerhouse has a diverse collection encompassing all sorts of technology including decorative arts, science, communication, transport, costume, furniture, media, computer technology, space technology and steam engines.


It has existed in various guises for over 125 years. It is now home to some 400,000 artefacts, many of which are displayed or housed at the site it has occupied since 1988.

The Powerhouse Museum houses a number of unique exhibits including the oldest operational rotative steam engine in the world, the Whitbread Engine.

Dating from 1785, it is one of only a handful remaining that was built by Boulton and Watt and was acquired from Whitbread's London Brewery in 1888. This engine was named a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1986.
