Church of St Marylebone

The Church of St Marylebone is a Grade I listed parish church located on Marylebone Road in the City of Westminster. It was built between 1813 and 1818 by architect Thomas Hardwick, with the chancel remodeled by Thomas Harris in 1883-84. Constructed from Portland stone with a slate roof, the church was initially designed as a chapel of ease, similar to Hardwick's St. John's on St. John's Wood Road, but was later expanded into a full parish church.

The church features an enlarged portico and a prominent steeple facing Marylebone Road, along with diagonally set porches that provide access from Marylebone High Street via a broad flight of steps. The design follows an Augustan "regular" classical style, reminiscent of Hardwick's mentor, architect William Chambers. The façade includes a giant hexastyle Corinthian portico with a pediment, a central architraved and consoled doorway, and flanking gallery doorways. The wings are adorned with Corinthian antae and doubled columns. A deep entablature and balustraded parapet complete the exterior.

The tower rises behind the pediment in three stages, featuring a square, rusticated clock stage that supports a Corinthian peristyled belfry stage topped with a domed cupola. Caryatids separate the semicircular arched lights of the drum, and the sides have semicircular arched windows with the main entablature returned over the chancel porches. Inside, Hardwick's nave has a flat ceiling and galleries on three sides with curved corners, supported by slender Ionic columns. The chancel, designed by Harris, is in the Italianate Renaissance style and contains numerous early 19th-century wall monuments. The layout of Regent's Park by John Nash opened up a fine vista of York Gate, aligned with Hardwick's portico.
