Holywell Street (London).
Fitzstephens, in his description of London in the reign of Henry II., speaks of the excellent springs at a small distance from the city, whose waters are most sweet, salubrious, and clear, and whose runnels murmur over the shining stones. Among these are Holywell, Clerkenwell, and St. Clements well.
