Work is well under way on a £5 million expansion project at an art gallery.
A new building is being constructed at the Harley Gallery at Welbeck, near Worksop.
Building work began on site in June last year and work has now started on the courtyard area.
It is due to be opened to the public next year.
The new space will house the Portland Collection – a collection of fine and decorative arts, built up over the centuries by generations of the Cavendish-Bentinck family.
The family, currently headed by William Parente, grandson of the 7th Duke of Portland, have lived at Welbeck for more than 400 years.
The new building will consist of a glazed entrance pavilion and two gallery spaces, with a fresh look for the courtyard.
It will be located alongside the Harley Gallery, within the walls of the Victorian Tan Gallop.
The area has recently been used for storage and was originally built as a covered area where the Welbeck Estate’s race horses could train in winter and poor weather. A portion of it has already been converted into artists’ studios.
