The actual site for the Battle of Bosworth has been located approx two miles from where the visitor centre is currently located. The location is being kept a secret until 20 Feb 2010 when all will be revealed at a special conference. A large number of medieval cannonballs and shot was found helping identify the site. All very timely for the current releases from the Perrys !!
have a look at the Battlefield trust web site for more detail.
