The bronze sculpture was erected in 1981. It is sited at the approximate location of John Wesley's conversion experience on 24 May 1738. The text is an excerpt from Wesley's journal.

I've slightly edited my original photo to increase contrast and sharpness and make it easier to read. I also recommend viewing the <a href="https://www.flickr.com/photos/alanstanton/48329375091/sizes/o/"> largest (original) size</a> photo. (As was customary in 1738, the tall/elongated letter 's' is written like a sloping 'f' without a bar.)

The sculpture is on a public walkway above the street outside the entrance to the Museum of London. This is located at the junction of Aldersgate Street and the road now known as "London Wall".

This refers to the few remaining parts of the original medieval city wall, which enclosed the area now known as the City of London. "The City" for short. The Museum is a short walk from Barbican tube station (London Underground). It's part of The Barbican Estate. This area was heavily bombed during World War II. It's in the Cripplegate ward of the City of London which was virtually demolished. By 1951 the resident population of the City stood at 5,324 of whom 48 lived in Cripplegate.

The estate was built between 1965 and 1976, on a 35-acre (14 ha) site that had been bombed in World War II. [...] The flats reflect the widespread use in Britain in the 1960s and 1970s of concrete as the visible face of the building."
