Isaac Newton’s Apple Tree at Woolsthorpe Manor, Lincolnshire, is one of the most historically important trees in Britain, a celebrated national treasure for over 300 years. It is believed to be the apple tree that inspired Isaac Newton in 1665 when the ‘notion of gravitation came to mind’ after he watched an apple fall. The tree, a rare variety Flower of Kent, fell over in 1820 but is still growing well having rooted where the trunk touched the ground.
