The Great Globe was restored last year as part of the project
A £5.5 million project to restore a Grade II-listed castle in a nature reserve in Dorset is set to begin.
Durlston Castle, near Swanage, is being renovated and turned into a visitor centre for the Jurassic Coast world heritage site.
It will be the centrepiece of the 280-acre Durlston Country Park and will house visitor services, a gift shop and catering facilities.
The castle is expected to open to the public next summer.
Poole firm Greendale Construction Ltd has been chosen as the main contractor.
Hamish Murray, Dorset County Council countryside ranger service manager, said: "The newly-restored castle will be a great asset to the whole area and we look forward to a successful opening in 2011."
As part of the project, the 40-tonne stone Great Globe, which was erected in the late 19th Century by George Burt, owner of the Durlston Estate, has been restored.
Specialists Sue and Lawrence Kelland carried out the work last summer.
