9 Pool Valley is a late 18th-century house and shop in the centre of Brighton, part of the English city of Brighton and Hove. Built as a bakery and shop for a local family, with two floors of living accommodation above, it later passed to another Brighton family who kept up the baking tradition until the mid-20th century. Since then it has had various commercial uses. Described as "one of the most famous surviving early buildings" in Brighton and "a charming relic",[1] the exterior is clad in distinctive black glazed mathematical tiles. English Heritage has listed it at Grade II* for its architectural and historical importance.
