I think this looks like a troll, a really evil troll. Or a goblin. Or a very nasty piece of dried fish. Oh go on, squint and see if you can see what I see - two eyes, teeth, gaping jaws, a nasty sneer...
Of course it's none of those things, it's a tree - and it's alive. It's a yew tree, ancient, hollow, and in some places missing branches which have been lopped - but it's still growing and will probably outlive all of us. Yew trees were sacred to the Ancient Britons which is why you find so many of them in churchyards - the yews were there first, the churches were built where the yews were in order to associate the religion with these sacred entities.
(Your pic is fine, Chavs - their parents can probably recognise those children from the back but I don't think anyone else can.
