The site is a place of worship and visitor attraction, incorporating the Museum of Methodism in its crypt and John Wesley's House next to the chapel.

The architect was George Dance the Younger, surveyor to the City of London, and the builder was Samuel Tooth, a member of Wesley's Foundery society.

[4] Around the gallery is motif in relief supposedly designed by Wesley: a dove with an olive branch in its beak encircled by a serpent following its own tail.

[4] Another major refurbishment of 1891 was carried out by Holloway Brothers, collaborating with the Methodist architects Elijah Hoole[8] and William Willmer Pocock.

[9] The location of the sanctuary (including the original communion table against the wall) in an apse behind the pulpit was common in the 'auditory' churches of the 18th century, but few other examples survive today.

The chapel was officially reopened on 1 November 1978, by Queen Elizabeth II and Prince Philip, Duke of Edinburgh.

In the dining room his Chamber Horse is set up which he used for exercise; on display in the study is his electric machine which was used for the treatment of illness.

[17] Wesley set up the first free dispensary in London giving out medical advice and remedies at his Foundery chapel.

His tomb is in the garden at the rear of the chapel alongside the graves of six of his preachers, and those of his sister Martha Hall and his doctor and biographer, Dr John Whitehead.

[18] A bronze statue of Wesley with the inscription "the world is my parish" stands at the entrance to the courtyard; created in 1891 by John Adams-Acton, the sculpture is Grade II listed.

[23] It provided medical facilities, legal advice, financial and dietary assistance, as well as religious services and musical events.

The Museum of Methodism, housed in the chapel's crypt, contains artefacts and relics relating to Methodism, including several of Wesley's speeches and essays on theology, the "warmed heart" "contemplative space", Thomas Coke's writing slope or desk and Donald Soper's portable preaching stand.
