Runcorn is a small industrial town in Cheshire, England, on the south bank of the River Mersey where it narrows at Runcorn Gap. In the town are the 60 buildings that are recorded in the National Heritage List for England as designated listed buildings in the current urban area of Runcorn, including the districts of Runcorn, Halton, Weston, Weston Point, and Norton. Two of these are classified as being in Grade I, nine in Grade II*, and forty-nine in Grade II. In the United Kingdom, the term "listed building" refers to a building or other structure officially designated as being of special architectural, historical or cultural significance. These buildings are in three grades: Grade I consists of buildings of outstanding architectural or historical interest; Grade II* includes particularly significant buildings of more than local interest; Grade II consists of buildings of special architectural or historical interest. Buildings in England are listed by the Secretary of State for Culture, Media and Sport on recommendations provided by English Heritage, which also determines the grading.
