Wicksteed Park has hosted annual fundraising walks for local charity Crazy Hats for almost two decades.
Following news of Wicksteed Park Limited's administration, Crazy Hat's founder, Glennis Hooper, said: "The 'home' of Crazy Hats for 19 wonderful years! Such sad, sad news. Our love and thoughts are with all our friends at Wicksteed Park.
"Thinking hats on now to try and save such a wonderful, wonderful attraction! Come on people of Northamptonshire, surely we can do this - we must!"
Here we take a look back at some of the memorable moments from Crazy Hats' annual walks.
