Grading

There are currently nearly 1450 sites included on the Register divided into three grade bands to give added guidance on their significance. The majority of the sites identified through the Register as being of a sufficiently high level of interest to merit a national designation, are designated grade II. Some sites, however, are recognised as being of even higher value. Around 30% of the 1450 are considered to be of exceptional historic interest and are awarded a star giving them grade II* status. A further 10% are of international importance, and are classified as grade I.
