Sheffield Council is to take over the running of the historic Bishop’s House from MuseumsSheffield.
The authority has pledged to maintain the same budget as it gave MuseumsSheffield to run the building last year.
Coun Roger Davison, cabinet member for culture, said: “We have protected this cultural gem from funding reductions. We are working extremely well with the Friends of Bishops House group and that will continue.”
Suggestions are believed to include the Friends group providing volunteers to help run the building.
