The Perilous Pond, sometimes spelt Perelous, was an ancient pond fed by a spring in London located near the junction of modern-day Old Street and City Road. It gained its name from many tragic drownings there of people using it as a swimming hole. It was also used by fishermen and wildfowlers . From 1790 there was also a small library and a bowling green attached. William Hone , the satirist, visited the pool in 1826 and described it thus:- The pool was closed in 1850 and built over. Its gives its name to the nearby Peerless Street and Bath Street and obliquely to the Old Fountain public house.
