Okay, so you know how sometimes people make things out of sticks and branches they find outside? Like a fort or a fairy house? Well, the Willow Man is a really big one of those!
He's made entirely out of willow branches, which are long and flexible, kind of like big pieces of spaghetti. The people who made him bent and twisted the branches together to make a huge sculpture of a man, with long arms and legs and a tall body.
The Willow Man is so big that he literally stands taller than some trees! He lives in a big open field in England, where lots of people come to visit him and take pictures. He's kind of like a giant outdoor art project that everyone gets to enjoy.
So, to sum it up, the Willow Man is just a really big statue made out of bendy sticks that lives in a big field in England.
