This iconic church on the edge of Trafalgar Square, known for its musical associations, is another of the works of architect James Gibbs and, as with St Mary le Strand, the current building was constructed in the first half of the 18th century to replace an earlier building.

The first references to a church on the site of the present building date back to the 13th century when, constructed upon a Roman burial site, it was apparently used by monks from Westminster. It was replaced by King Henry VIII around 1542 and enlarged in 1602 before finally being demolished in 1721.

Gibbs’ apparently first suggested the design feature a round nave with a dome over the top but the proposal was rejected as too expensive and a simpler, rectangle-shaped church was subsequently agreed upon and eventually completed in 1726. Part of the design inspiration comes from Sir Christopher Wren, although Gibbs’ integration of the tower into the church was a departure from Wren’s designs (the church spire rises 192 foot into the air).

Among the features of the interior are ceiling panels in the nave which feature cherubs and shells and are the work of ceiling experts Giuseppe Artari and Giovanni Bagutti. Other items of interest include Chaim Stephenson‘s sculpture, Victims of Injustice and Violence, remembering all victims during apartheid in South Africa (it was dedicated by Desmond Tutu in 1994), a statue of St Martin and the Beggar by James Butler, and, on the porch, Mike Chapman‘s sculpture marking the millennium, Christ Child. Paintings include one of James Gibbs himself by Andrea Soldi and dating from 1800.

Among those buried in the church are furniture-maker Thomas Chippendale, sculptor Louis-François Roubiliac and notorious robber Jack Sheppard (he’s buried in the churchyard). The crypt also contains a life-sized marble statue of Henry Croft, London’s first pearly king, which was moved there from St Pancras Cemetery in 2002.

As well as being the location of the first religious broadcast, its musical heritage includes performances by Handel and Mozart and being the location of the first performance of its namesake chamber orchestra, the Academy of St Martin in the Fields.

Since the early 20th century, the church has been noted for its work with the homeless (thanks in particular to the work of Vicar Dick Sheppard). Meanwhile, its connections with music – which date back to its rebuilding – continue in the concerts held in the crypt cafe. The crypt also hosts art exhibitions.

The church underwent a £36 million renewal project in the Noughties. Additions included the new east window by Shirazeh Houshiary.
