Work to rehouse South Yorkshire’s main display of military history means disruption at a museum.
The York and Lancaster Regimental Museum has been homeless since its old base in the former Rotherham library closed last year.
It is due to reopen in Clifton Park Museum in January.
Work to create a home for the museum at Clifton Park means disruption from Monday - although the venue will not close during the work, which had originally been planned.
A Rotherham Council spokeswoman said: “From Monday, only the ground floor of Clifton Park Museum, including the shop, café and the archives and local studies searchroom, will be open.
“Several of the upper floors of the museum will re-open on Monday, November 4 whilst the remainder will stay closed until the middle of January 2014 when the York and Lancaster Regimental Museum and the revamped Victorian galleries will open.
“No further closure is planned in order to complete the remaining work and can be completed whilst the unaffected areas of the museum are open.”
She added: “The opening of the York and Lancaster Regimental Museum has been delayed due to problems with the supplier of the exhibition cases.”
