Remains of an ancient settlement in Derbyshire are to be protected after suffering damage from illegal off-road vehicles and flytipping.
Pin Dale near Castleton has remains of leadworks dating back about 2,000 years as it was a place where early miners used picks to remove lead ore.
Fences and barriers are going up to prevent further damage in the Peak District National Park site.
Walkers will still have access and grazing animals will be reintroduced.
Ken Smith, cultural heritage manager for the Peak District National Park Authority, said: "The site has been particularly vulnerable because it lies near an unsurfaced track which is legal for vehicles and trail bikes.
"Irresponsible drivers and riders have used it as a race track or a rubbish dump, ignoring, or at times, destroying signs asking them to avoid the sensitive site," he said.
It is hoped the protective measures will allow grassland habitats to recover and rare plants and flowers that grow in the area to thrive again.
