Councillors in Edinburgh have voted to demolish Meadowbank Stadium and replace it with a smaller arena.
The ruling Lib Dem/SNP coalition was supported by the Conservatives, as 39 councillors voted for the proposals.
Under the plans, the 16,000 seater stadium will be replaced with a 5,000 capacity arena, and some of the land will be sold to housing developers.
The Save Meadowbank Campaign said the council's decision went against the wishes of the electorate.
Money from the housing development will be used to help pay for the new £25m stadium, along with grants.
Campaign spokesman Kevin Connor said: "The current facilities are hugely popular and need to be increased to cater for demand - but instead the council has decided to reduce capacity.
"The plans presented today include no provision for outdoor football pitches.

"There is no throwing area, no warm-up area for athletes and no athletics storage facility.
"As for the cyclists, they have been told to get on their bikes."
Liberal Democrat sports spokeswoman Marjorie Thomas, said: "Originally I had hoped we could refurbish the existing buildings but I have been convinced that this would not be value for money and cannot be justified."
Lib Dem councillor, Gary Peacock, voted for a Green Party amendment calling for the site to be retained for sports use.
He said: "I think a sale of this scale is unacceptable."

On top of the £25m construction costs, it is thought about £5m would be spent on fitting out and developing the new centre.
