A rare, wild cattle herd could be under threat over plans to build a deer hunting lodge, it is being claimed.
Campaigners believe the cattle would be disturbed by hunters
Developers want to put the lodge on woodland at Kay Hill near to the Northumberland Chillingham Castle herd.
But campaigners claim the 56 cattle, which are believed to be related to the prehistoric auroch oxen, will be disturbed by hunters and traffic.
On Tuesday evening Berwick Council will hold a meeting to hear evidence from those for and against the move.
The lodge, which is being proposed by Hertfordshire-based Michael Glasser, would sleep up to 10 people.
Sir Humphrey Wakefield, owner of Chillingham Castle, said the traffic going to and from the lodge would ruin the tranquillity of the area.
He said: "The wild cattle are in a remote area and visitors can get lost in the mists of time - but an avenue or road through this park with trucks and cars on it would ruin the 'lost in time' experience."
A Berwick Council report said the proposal had drawn 20 letters of support compared to 13 against. A spokesman for the developer said no comment was being made until after Tuesday's meeting.
According to the Chillingham Wild Cattle Association, the herd has remained isolated and untouched next to Chillingham Castle since it was first penned into the park in 1260 AD.
The Association also said the herd was the only one in the world to have remained pure with no outside blood ever being introduced.
