Kinneil Museum in Bo’ness will be closed from Monday toi allow improvements to be carried out.
The work has been made possible through funding from Falkirk Council and will include making the museum more accessible for people with disabilities.
The toilets will be upgraded and a ramp installed up to the front door.
As the work is planned to last until May 4, it will not be possible to open the museum to coincide with the opening of Kinneil House on April 21-22 for a family event organised by Historic Scotland with the support of The Friends of Kinneil.
However, visitors will find plenty to enjoy over that weekend both in the house and around the estate.
The museum will re-open on Wednesday May 9.
Kinneil Museum is located in the 17th century stable block of Kinneil House and acts as an interpretative centre for Kinneil Estate.
The ‘2000 Years of History’ exhibition tells the story of the park from Roman times to the present day.
Antoninus Pius, St Serf, Mary, Queen of Scots and James Watt are among the many historical characters associated with the estate.
