Parking charge plans for Plymouth's Saltram House
The National Trust is considering introducing car parking charges as part of plans into managing a Grade I listed property near Plymouth.
The Georgian mansion Saltram House, is which surrounded by landscaped parkland, is a popular attraction.
The trust said the parking proposals had not been approved.
It added that it was carrying out a consultation to find out how people used the car park at Saltram as part of its future plans for the estate.
The mansion was built in the middle of the 18th Century, incorporating parts of a Tudor house that was already on the site.
Trust Devon area manager John Longworth-Krafft said that the charge was only a proposal at this stage.
He added: "People need to remember that access on foot and cycle will remain free.
"There are a lot of people who do that."
Members of trust also had free access, he said.
The trust already charges for parking at some other Devon properties, including Killerton, at Broadclyst, near Exeter, where it costs £2.50 a car.
It also charges at beach car parks, including Wembury, near Plymouth.
The trust said money raised went back into maintaining beaches and headland.
