Ahead of that visit, we’re looking back at his connection to this long-running charity and how William’s patronage connects with his grandfather, The Duke of Edinburgh. Fields in Trust was founded in 1925—then known as the National Playing Fields Association—by the Duke of York (later King George VI), who served as its first President. Its mission is to protect parks and green spaces in perpetuity, which provides social, mental and physical health support to those who use these spaces.
