Flask Walk is named after the Flask pub. Here, in the 18th century, the area’s therapeutic spa water was put into flasks and sold to visitors or sent to London. The water, rich in iron salts, came from nearby Well Walk, where a disused fountain now marks the site of the well. There have been many notable residents of Well Walk: artist John Constable, novelists D H Lawrence and J B Priestley, and the poet John Keats. At the High Street end, Flask Walk is narrow and lined with old shops. Beyond the Flask pub it broadens into a row of fine Regency houses.
