For more than 25 years the Friends campaigned for a museum in Windsor.

Through their determination and hard work in fund-raising, promoting, and petitioning, in 2010 a museum was granted, for and about the people and town of Windsor. Housed on the ground floor of the Guildhall, the museum was opened to the public at noon on Saturday, 12th March 2011. It was officially opened on Friday, 9th December 2011 by Her Majesty, Queen Elizabeth II.

Since then the Friends have continued their championing of the museum through fund-raising, volunteering, events, and supporting the work at the museum store.
