One of Manchester’s most iconic museums will be upgraded, thanks to a multi-million pound investment.

The Science and Industry Museum, in the heart of the north-west city, will be the recipient of a £6 million donation from the Department for Digital, Culture, Media and Sport.

The cash injection is being given to celebrate the museum’s 50th anniversary, and will be used to restore the Power Hall – which showcases the largest collection of working steam engines in Europe – to full working condition.

Having been built in 1855, the Grade II-listed building is in need of some attention, and work to restore it is expected to take two years.

Sally MacDonald, director of the Science and Industry Museum, said: “This project will allow us to not only carry out much-needed repairs, but also transform the Power Hall into a multi-sensory gallery showing how Manchester provided the power that changed the city and the world.”

Arts minister Rebecca Pow added the refurbishment of the Power Hall will help to “celebrate Manchester’s industrial history and inspire the engineers of the future”.

The building was originally the shipping shed for Liverpool Road Station, which was the world’s first purpose-built passenger rail hub. The investment will allow major repair work to be carried out to its roof, as well as enable the redisplay of artefacts.

Manchester’s famous museum also hit the news earlier this year after it received planning permission for a Special Exhibition Gallery.

The museum display cases will be featured in the Grade II-listed New Warehouse, the main building and arrival point. This will allow temporary exhibitions of an international standard to be shown in the city, helping to boost the museum’s significance on a global scale.
