Former Church of St Luke United Church

Former Moravian chapel, later known as St Luke's United Church and now The Quarry Theatre at St Luke's, located on the north side of St Peter's Street in Bedford. Built in 1864 by James Horsford, it replaced an earlier chapel of 1745.

The building is constructed in gault brick with stone dressings and is planned as a square with an apse to the north. The façade features three central projecting bays with stone quoins. A large tripartite round-arched window is positioned centrally, flanked by two smaller two-light windows, all with enlarged keystones to the arched brick heads. A stone string course doubles as a central transom to the windows. Above the string course, stone columns flow into round-headed tracery. Above the windows sits a pediment with moulded stone dressings on a modillion cornice, which has a central roundel. To each side of the projecting façade is a lower entrance bay, probably serving as separate entries for men and women, each with a timber door having a moulded stone surround and a large round-headed light above. On the first floor is a single light with stone columns and leaded light windows that appear original. The side elevations feature window openings with contrasting brick dressings, matching the form on the façade. Diamond light fenestration in the apse and main body dates to 1885 and 1864 respectively.

The interior retains significant features. The apse has a rounded, coffered ceiling and contains late 19th-century choir pews and the remains of an 18th-century organ screen and pipework, altered and restored in the 19th and 20th centuries. A proscenium arch framed by simple pilasters and a projecting cornice faces the congregation. Most original pews have been replaced by chairs, though some remain on the east and west sides and at the rear. On the east wall are panels in the lower window recesses, donated by GB Lutyens (of the same family as EL Lutyens) to commemorate Reverend Hasse becoming Bishop of the Moravian Church in 1904. The panels bear painted lettering citing scripture and the Ten Commandments. The ceiling of the main body is coffered with good quality detailing. A gallery, supported on elegant iron columns and approached by stone stairs on either side with iron balustrades, spans the rear. The gallery retains a complete set of segregated and ramped pews.

The Bedford Moravian settlement was established from 1745 and occupies much of the north side of St Peter's Street east of St Peter's Green. It comprises a former Single Sisters House, Manse and Single Brothers House (later a Moravian school and since 1921 known as the Howard Building of Bedford School) all dating to the mid-18th century and grade II listed, together with a grade II listed teachers house of circa 1830 at 30-32 St Peter's Street.

An 18th-century organ originally located in St Paul's church in Bedford was moved to the chapel after its completion. The organ was originally built in 1715 by Gerard Smith, a noted organ builder whose surviving instruments include the university organ in Great St Mary's Church, Cambridge. At the Moravian church it was subsequently altered and restored in the 19th and 20th centuries. Although Smith's mechanism has not survived, some of the metal pipes in the main case and the case itself are 18th-century work.

A church hall was added to the east in 1998 and has no historic interest.
