For an unnoticed set of hill along the Leicestershire/Northants border they do have one claim to fame. They represent the border between the River Severn, the Wash and the Humber. This might seem a strange thing to claim as the hills are miles from the sea but it is true. When the rains falls on these hills it will eventually flow east via the River Welland to the Wash, North via the River Soar and River Trent to the Humber and westward via the River Avon to the Severn Estuary.
Of course the hills have one other, far more unwelcome, claim to fame. They are the site of the battle of Naseby that raged through the rolling countryside. You can decide which is more important.
