It replaced a chapel built in 1878–1879 that was destroyed in World War II during the air raids in September 1940.
The congregation had moved there in 1879 from nearby Jewin Crescent, a site now incorporated into the Barbican.
The Jewin Crescent chapel had opened in 1822, following a move from Wilderness Row, Clerkenwell.
The current building was designed by Caroe & Partners[2] in a Swedish-inspired form of modern architecture sometimes called the New Humanism.
After a dramatic fall in the congregation, in 2013 the London-based BBC News presenter Huw Edwards, who occasionally substituted as the chapel's organist, agreed to lead a campaign to save the building and the chapel, to keep the traditions of the London Welsh community alive.
