The Baylis Gallery at the Park Street centre has a wealth of royal memorabilia on show until the end of March.
Items include coronation mugs and tins and memorabilia from the investiture of the Prince of Wales in 1969, the Silver Jubilee in 1977 and the Golden Jubilee in 2002.
There are also scores of photographs, most from the archive of the Maidenhead Advertiser which record visits to the Maidenhead area by the Queen and other members of the royal family from 1940 until 2011.
Chairman Richard Poad (pictured) said: "There is a model of the coronation procession complete with lifeguards and yeomen of the guard, and from members of Windsor and Maidenhead Embroiderers Guild have come a number of superb embroideries on a Diamond Jubilee theme.
"Finally there are two photo albums of royal visits to the Maidenhead area for visitors to browse."
The centre is open from 10am-4pm, Tuesdays to Saturdays. The exhibition ends on Saturday, March 31.
