 It is the widest alley in the old town.The alley, mentioned as "brundzgrenden" in 1526, is named after a water well mentioned in 1461, when a blacksmith named Henrik was paid for having "forged on the well on 'Fisherman's Square'" ("smidat till brunnen på Fiskaretorget").Historically, wells in cities were located in open spaces, and, oddly enough, neither a well or a square can be found near the present alley.
