"For centuries Meriden, to the west of Coventry, West Midlands, held the claim to be the geographical centre of England, and there has been a stone cross there commemorating the claim for at least 500 years. The justification is that the point farthest from the sea is in the vicinity of Meriden. A rival claim for the true location of the centre of England is made by the site of a tree, the Midland Oak, situated on the boundary between Lillington and Leamington Spa, Warwickshire"
