The Yorkshire Sculpture Park, which is filled with work by artists including Henry Moore and Tracey Emin ,has been named Museum of the Year.
The 500-acre open-air gallery , near Wakefield, was hailed by judges as a "truly outstanding museum with a bold artistic vision".
The park, which opened more than 30 years ago with an exhibition of 31 sculptures, welcomes 300,000 visitors a year to its galleries in the grounds of an 18th century country house.
It beat venues including Tate Britain and the Mary Rose Museum in Portsmouth to the win the £100,000 prize, formally known as The Art Fund Prize for Museum of the Year, at a ceremony at the National Gallery in central London.
Oscar-winning director Sam Mendes announced this year's winner and praised the "dedication, love, and unbelievable creativity" of the shortlisted museums which also included London's Hayward Gallery and the Sainsbury Centre for Visual Arts in Norwich.
Stephen Deuchar, who chaired the judges, said: "A perfect fusion of art and landscape, the Yorkshire Sculpture Park has gone from modest beginning to one of the finest outdoor museums one might ever imagine."
The Yorkshire Sculpture Park has seen some unusual exhibitions in its 30-odd year history. But there has been nothing quite like the latest collection at the open-air gallery at West Bretton Bretton, near Wakefield.
Curator Helen Pheby is responsible for bringing the walking sculptures by artist James Capper to the Yorkshire Sculpture Park near Wakefield. She says they all felt a real sense of excitement when they saw the items which they would be taking delivery of for the next three months.
The sculptor who has designed a series of walking pieces of art which are going on display at the Yorkshire Sculpture Park says it is amazing to see his work in the open air. James Capper has built the mechanical objects which he drives around the park, leaving tracks across the grass.
Several walking sculptures have arrived at the Yorkshire Sculpture Park near Wakefield where they will spend the next three months travelling around near the other exhibits. The pieces by sculptor James Capper are designed to churn up the ground around them, leaving behind an artistic trail.
