The Discover Downham Heritage and Learning Centre will be opening its doors to the public for the first time at Easter.
On Monday, March 28, residents and visitors will be able to discover more about the history of the town.
It is hoped the centre, in the Old Fire Station, in Priory Road, will become a hub for tourists and schools.
Chairman of the Downham Market and District Heritage Society, Dave Flower, said: “This is an exciting time for us, as we can see years of hard work by our volunteers coming together to provide this vital asset for the local community.”
The society raised £650,000 from the Heritage Lottery Fund, Wren (a non-profit organisation which distributes grants from environmental tax credits) and other charitable organisations to bring project to life for the benefit of the town.
Mr Flower, added: “We are very grateful to our funders, the Heritage Lottery Fund and Wren for all the support they have given us.”
Volunteers have spent the last few months putting new displays together which focus on Fenland life and the development of the town over the years, including trade, industry and shops.
On the opening day, which is Easter Monday, there will be family activities available from 10.30am to 11.30am and 2pm to 3pm.
Refreshments will be available for visitors.
After the opening day, the centre twill be open Thursdays, Fridays and Saturdays 10am to 4pm and is free to visit.
It will also be available for groups and societies to hire to hold events.
