Supporters of a museum in Derby city centre have been protesting against possible cutbacks.
Architect Joseph Pickford used his house to showcase his skills
The city council announced that, from April, Pickford's House on Friar Gate will only be open to pre-booked groups, as there is not enough passing trade.
The friends of Derby Museums and Art Galleries demonstrated on the streets of Derby on Saturday.
They collected signatures on a petition they intend to hand to the city council on Monday.
Chairman of the Friends of Derby Museum and Art Gallery Derek Limer said the Georgian house was being "mothballed".
"In 2005 I think around 21,000 people visited, of which only about 2,000 had pre-booked and most of those were school parties," he said.
"(The council's) argument is that they don't get a sufficient number of visitors. Our argument is that they should promote it.
"We think it's important a city the size of Derby should have its museums available for visitors when they come."
Mr Limer plans to raise the matter at a full meeting of Derby City Council on Wednesday.
Derby architect Joseph Pickford built the house as his own home in 1760, using it as an example of his work to visiting rich clients.
