OK, admittedly this isn’t the actual tree and there’s no real proof that it’s the descendant of the actual tree, but Cambridge University says that it is and that’s good enough, right?
Isaac Newton himself often told a story that a falling apple from a tree helped him to form his theory of gravitation, first published in 1687. Whether or not the apple actually hit him on the head is a subject of some conjecture, although modern-day cartoonists have adopted this version of events as their favourite.
The tree in Cambridge is grown from propagation from the one in Woolsthorpe Manor, which died in the nineteenth century. It sits in the University’s 40-acre Botanic Garden, a great visitor destination in its own right.
The plaque below the tree reads " Sir Isaac Newton's Apple This apple tree is a descendant by vegetative propagation of a tree which grew in the garden of Woolsthorpe Manor, near Grantham, and which is reputed to be the tree from which fell the apple that helped Newton to formulate his theory of gravitation. The original tree is said to have died about 1815-1820. The variety is 'Flower of Kent'. "
