There are 67 Grade I listed buildings in Cambridge, England. In the United Kingdom, a listed building is a building or structure of special historical or architectural importance. These buildings are legally protected from demolition, as well as from any extensions or alterations that would adversely affect the building's character or destroy historic features. Listed buildings in England are divided into three categories—Grade II buildings are buildings of special interest; Grade II* buildings are Grade II buildings of particular interest; and Grade I buildings, which are those of "exceptional" interest. Only around two per cent of listed buildings are given Grade I status.[1]
