Tucked behind busy Oxford Street lies this gem of High Victorian Gothic architecture, designed by William Butterfield and completed in 1859.
Purists complained that Nash blithely confused different architectural styles, but it was designed for maximum impact, to provide an eye catching monument for the newly laid out Regent Street.
Constructed in Bath stone, which glows in the evening sunlight, it has a grand columned circular portico reminiscent of a classical temple, surmounted by a fluted spire. Inside is a large open hall with a wide nave surrounded by a gallery on three sides.
At the east end, a spectacular painting of Christ hangs under a huge golden sunburst, one of the finest of its kind in England.
