Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, near Grantham, Lincolnshire, is the birthplace and family home of Sir Isaac Newton. He was born here on 25 December 1642- at that time it was a yeoman’s farmstead, principally rearing sheep.
Newton returned to Woolsthorpe Manor in 1666 when Cambridge University closed due to the plague, and it was from here that he performed many of his most famous experiments, most notably his work on light and optics. This is also the site where Newton, observing an apple fall from a tree inspired Newton’s theory of gravity.
Woolsthorpe Manor is now in the hands of the National Trust and open to the public all year round.
