Campaigners against plans for housing near historic Culloden Battlefield are to bring their protest to the streets of the Highland capital.
Activists who gathered at Holyrood last month now propose to stage a demonstration at the historic site and in Inverness city centre.
A date is yet to be set but it is hoped that hundreds of people will join the rally.
The move comes as it emerged that the Battlefields Trust has written to First Minister Alex Salmond, asking him to intervene and review the decision to approve the houses.
The charity campaigns across the UK to protect battlefields from inappropriate development.
Inverness Properties’ proposals for 16 homes at Viewhill Farm at Culloden outside Inverness were originally turned down by Highland councillors last year.
But the firm won its appeal to the Scottish Government last month.
Protestors claim that the move sets a dangerous precedent which could lead to more development on the site, where the Jacobite rebellion was crushed in 1746.
Chairman of the Battlefield Trust, Frank Baldwin, said that they were “strongly opposed” to building homes near the battlefield.
He said: “We see this as the thin end of the wedge.
“Whilst the site for housing at Culloden already has farm buildings on it, allowing houses there risks giving a green light to developers to push through plans to build inappropriately on battlefield brownfield land at Culloden and elsewhere in Scotland.
“Visitors don’t want to see modern urban sprawl destroying their views and disrupting their understanding of Scottish battlefields.”
Mr Baldwin added: “The Battlefields Trust has written to the Scottish Government asking it to reconsider the decision and, in the event it refuses to relent, to give public assurances that in no way will this give carte blanche to developers to build on brownfield battlefield sites.”
There was no response from the Scottish Government yesterday.
The proposed development site is on the edge of the Historic Scotland inventoried battlefield, which is owned by the National Trust for Scotland.
While the National Trust for Scotland objected to the proposals, Historic Scotland did not.
Meanwhile, Highland Council has written to the developers to object to a large bill for expenses.
The local authority was ordered to pay expenses for the appeal, amounting to £18,180, including the VAT.
