The Yorkshire Museum is a museum in York, England. It is the home of the Cawood sword, and has four permanent collections, covering biology, geology, archaeology and astronomy. It underwent a major refurbishment from November 2009 to 1 August 2010, with major structural changes and a re-development of all existing galleries. The Museum was founded by the Yorkshire Philosophical Society to accommodate their geological and archaeological collections, and was originally housed in Ousegate, York until the site became too small.
In 1828 the society received by royal grant, ten acres of land formerly belonging to St Mary’s Abbey in order to build a new museum. The main building of the museum is called the Yorkshire Museum and was designed by William Wilkins in a Greek Revival style. It is a Grade I listed building. It was officially opened in February 1830, which makes it one of the longest established museums in England. A condition of the royal grant was that the land surrounding the Museum building should be a botanic gardens; this was done in the 1830s, and they are now known as the Museum Gardens.
The Tempest Anderson Hall was built in 1912 as an annex to the museum, and is an early example of a reinforced concrete building. It is used as a conference venue and lecture theatre. In 1960, the Museum along with the Museum Gardens, were given in trust to York City Council, its successor the City of York Council in 2002 set up the York Museums Trust to manage the York Castle Museum, York Art Gallery, the Yorkshire Museum and the Museum Gardens.
