Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, near Grantham, is a typical seventeenth century yeoman's farmhouse, famous as the birthplace and family home of Sir Isaac Newton Link . He was born there on 25 December 1642.

Newton returned here in 1666 when Cambridge University closed due to the plague, and it was here he performed many of his most famous experiments. Due to his achievements in mathematics, optics and mechanics in this period, 1666 has been called the Annus Mirabilis - his marvellous year. There is strong evidence that some of the optical experiments with prisms were done in the study at Woolsthorpe, and it is also believed that the orchard was the site where Newton observed an apple fall from a tree Link , inspiring him to formulate his law of universal gravitation.

The manor was purchased by the National Trust in 1943 and is furnished as a 17th-century farmhouse might have been when Newton lived there. It is open to the public all year round Link (National Trust).

The farmhouse is a grade I listed building (English Heritage Building ID: 193262 Link British Listed Buildings) as are the stables
