St Mary's, Bryanston Square

St Mary's, Bryanston Square, is a Church of England church dedicated to the Virgin Mary on Wyndham Place, Bryanston Square, London. A related Church of England primary school which was founded next to it bears the same name.

History
St Mary's, Bryanston Square was built as one of the Commissioners' churches in 1823–1824 and was designed by Robert Smirke to seal the vista from the lower end of Bryanston Square. It is a brick building, with a rounded stone portico, round tower and small dome, topped by cross. It is listed in the top protective and recognition category, grade I. The church cost £19,955, towards which the Church Building Commission gave a grant of £14,955. The northern side faces onto York Street.

Charles John Gardiner, 1st Earl of Blessington, and Margaret Farmer were married in the church. Thomas Frognall Dibdin (c. 1823 – 1847) was a rector, and Samuel Augustus Barnett was introduced to his future wife Henrietta during his curacy there (1867–68).

Modern era
The church is known colloquially as "St Mary's Church London", since it is the most central Anglican church named St Mary's in inner London, and is known to be an active element of the evangelical wing of the Church of England.

The current congregation led by Rev'd John Peters began meeting in the building in 2002, having received allocation of the building from the Bishop of London. Most of the starting congregation moved from St Paul's Onslow Square, having met there under the name St Paul's Anglican Fellowship following reorganisation at Holy Trinity Brompton & St Paul's Onslow Square.

Services
The church runs two services on a Sunday: an informal 11am service, with groups for children and youth, and an informal 5:30pm service for all ages, but catered slightly towards young professionals.

Groups and courses
The church runs several midweek groups and courses, aimed at a wide variation of people.

Life Course
The Life Course is an eight week course run three times annually, which aims to enable participants to explore the various meanings assigned to life. The aim of the course is to provide an open platform to discuss viewpoints and explore more than would be typically catered for in a church service or outreach course. As such, it does not require any particular belief or faith. Those who would describe themselves as agnostic or atheist are just as welcome as those of the Christian faith as well as other faiths: in the past, members of the Sunday Assembly have undertaken the course.

Participants meet downstairs in the church hall for dinner, following which an introductory presentation is made, aiming to stimulate discussion in smaller groups. Over the course, themes include: "What meaning do we give our lives?", "Where do people look for meaning?", "What evidence is there that true meaning can be found?" and "What difference does true meaning make?" alongside others. The course also includes an optional weekend away.
