It comes after a recent inspection.
Quainton Parish Council say after a visit by Historic England, they've been advised that due to existing cracks and movement within the structure, they should minimised any additional strain.
The Medieval standing cross is located on the green in the village, and according to Historic England's information on standing crosses, would've been put up between the mid 10th and mid 16th century. They were used for a variety of functions including as outdoor procession stations for churches, to mark boundaries to commemorate battles.
They say less than 2,000 medieval standing crosses, with or without cross-heads, are now thought to exist.
The condition of.Quainton's cross is still being assessed, but the parish council are asking residents and visitors to avoid climbing, sitting, or standing on the monument.
They say it will help protect the important part of Quainton's heritage and prevent any further deterioration while specialist advice is sought.
