A sculpture by dissident Chinese artist Ai Weiwei intended to provoke discussion about migration and refugees is on display at Britain's Blenheim Palace. The <a href="https://www.thenationalnews.com/arts-culture/ai-weiwei-s-new-york-project-asks-how-much-we-have-grown-used-to-barriers-1.672972">seven-metre-tall <em>Gilded Cage</em></a> is meant to portray the physical and psychological constraints of life as a refugee. Unveiled on Wednesday in the grounds of Winston Churchill's Oxfordshire birthplace, it is expected to stay on long-term view in the palace gardens. The artwork previously stood at the gates of New York City’s Central Park after it was put on display there in 2017, its prison-like fences jarring intentionally with the beautiful surroundings. Ai Weiwei, 63, <a href="https://www.thenationalnews.com/arts-culture/art/citing-intolerance-chinese-artist-ai-weiwei-decides-to-leave-germany-1.897789">moved to Britain from Germany in 2019</a> and has long highlighted the plight of refugees and migrants in his artwork. In March he said he planned to stay in Portugal long term while keeping a base in the UK and a studio in Berlin. The artist left China in 2015 after falling foul of a regime that arrested him at Beijing's airport in 2011 and held him for 81 days without explanation. He previously had a hand in designing the famous Bird's Nest stadium that formed the centrepiece of the 2008 Beijing Olympics. <em>Gilded Cage</em> is on display on the south lawn at Blenheim Palace, which previously hosted a display of Ai Weiwei's art in 2014. The palace and its park, the centuries-old home of the Dukes of Marlborough, became a Unesco World Heritage Site in 1987. Winston Churchill, a descendant of the first duke, was born at the palace in 1874.
