The National Trust for Scotland (NTS) has said it may seek a judicial review.
A conservation charity that protects and promotes Scotland's natural and cultural heritage has said it is “shocked and disappointed” by a council decision to approve a racing track near the site of the Battle of Bannockburn.
Councillors in Stirling approved plans for a trotting track for harness racing to be built on land on the outskirts of Stirling.
The National Trust for Scotland (NTS) had objected to the plans originally, and following the approval have called for ministers to intervene and for the Scottish Government to block the move.
The now-approved development is proposed to have 200 cars and access roads within view of the battle site.
Councillors were warned by the NTS that the development could result in an "elevated risk of collision on the main road, endangering residents and visitors", with a further warning that noise from the track could "greatly detract from the visitor experience at a nationally important historic site".
NTS have now said they may seek a judicial review of how the planning application was handled.
Stuart Brooks, director of conservation and policy at the charity, told BBC Scotland: "This development will have a significant adverse impact on the nationally designated Battlefield of Bannockburn, a heritage site of national and international importance and part of our national identity.
"The development will not only damage internationally significant heritage but will fundamentally alter the experience of the site for current and future generations.
"Following Stirling Council's approval, we ask that Scottish government ministers consider our concerns on behalf of the nation and call in the application for proper scrutiny and their own determination."
A Stirling Council spokesperson told the BBC: "The panel carefully considered all information relating to the planning application in making its decision."
A Scottish government spokesperson told the BBC: "We understand that Stirling Council is minded to approve the proposal for the trotting track.
"The application will be notified to ministers who will decide whether or not to call it in for their own determination."
