The introduction of parking charges on a Poldark filming site where 31 men died nearly 100 years ago in a mining disaster has been defended by the National Trust.
Opponents say "public feeling is high" about the ticket machine at Levant Mine in Cornwall.
The machine was wrenched out of the ground on 4 February but will be replaced on Thursday.
The National Trust said the fees fund conservation and maintain the site.
Scenes from the first series of Poldark were filmed at Levant Mine, and the National Trust said there had been a 50% increase in visitor numbers to 100,000 people a year since the drama was first broadcast in March 2015.
Ian Cooke created a Facebook group against the move by the National Trust and posted an open letter on the site, reading: "The National Trust have still not taken on board public feelings about the new charges as applicable to Levant, but hope they eventually see sense and abandon this policy as it applies to the very special case of Levant due largely to the disaster of 1919.
"Public feeling against this new policy is running very high locally and, to prevent a repeat of unsightly and costly vandalism, I once again appeal to the National Trust to reconsider their parking policy and agree to grant an exemption for this location."
He also told the BBC: "We don't want Levant Mine to be treated as a Poldark attraction."
Ian Marsh, from the National Trust, said: "A terrible tragedy happened in 1919 where 31 men lost their lives there.
"We know people still come to pay their respects, those that descend from the miners that lost their lives, and we don't want to prevent that from happening in any way.
"Those people are able to park for free and while they're with us we want to hear their stories and hear their memories of the place."
