Woolsthorpe Manor

Sir Isaac Newton fans may feel the gravitational pull of the great man's birthplace, about 8 miles south of Grantham. The humble 17th-century house contains reconstructions of Newton's rooms; the apple that inspired his theory of gravity allegedly fell from the tree in the garden. There's a nifty kids' science room and a cafe. Take Centrebus 9 from Grantham (£2.80, 20 minutes, four per day Monday to Saturday).
