Trim Street in Bath, Somerset, England. This historical street was built in 1707 and contains many listed buildings. A listed building in the UK is one which has been placed on the (bow or curtsy before you read this) Most Anciently and Awfully Magical Statutory List ofBuildings of Special Architectural or Historic Interest. (okay those first five words are mine) A listed building may not be demolished, extended or altered without special permission; and it’s what keeps cities like Canterbury from ending up looking like Slough. Most structures appearing on the lists are buildings, although bridges, monuments, sculptures, mileposts, and even the Beatles’ Abbey Road pedestrian crossing is Listed.
