Under 'Dome Concert Hall & Pavilion Theatre': "The complex surrounding the Dome conveys the impression of being the product of a sustained building campaign in consistent style, but it is actually the work of a number of different hands and periods. The Dome itself (not so called until the mid-1850s) was a rotunda stable, designed by William Porden in 1804 in the ‘Hindoo’ manner, and built to serve the Prince Regent's Brighton residence, the Pavilion. It was this stable building which set the Islamic style, later to be adopted in spectacular fashion for the remodelling of the Royal Pavilion itself. Alongside was a Riding School, now the Corn Exchange. The Museum and Library which make up the remainder of the complex, were added by Philip Lockwood in the 1860s & 70s, and modified and extended by Francis May in 1901-2. The stables were converted into a concert hall with a magnificent polychrome Saracenic interior by Lockwood in 1867, but the whole of his work was lost or obscured when Robert Atkinson removed an inner ring of columns and constructed a new interior in cine-modern style in 1934-5. Atkinson also built a new Church Street entrance for the Corn Exchange (by this time used for a multiplicity of purposes) and a supper room doubling as a concert room (now the Pavilion Theatre) on the south west, New Road, corner of the site. As seen now, the complex contains three performance spaces: the Dome Concert Hall, the Corn Exchange and the Pavilion Theatre. The least altered is the Corn Exchange, still a flat-floored multi-purpose room, recognisably Porden’s Riding School, a fine space with an elliptical roof in one span without tie beams. A gallery entrance to the Pavilion Theatre was added near the south end by Atkinson. The Dome Concert Hall is much as Atkinson left it, a circular domed interior, interesting of its date but now inadequate in both its stage dimensions and its acoustic performance. May's magnificent tiled entrance remains in altered condition. Atkinson’s Pavilion Theatre presents a simply massed façe to New Road, with minimal ornament faintly echoing the Islamic style of its neighbours. It is disappointing in having no public entrance from the street, where it could have intensified evening activity in the vicinity of the nearly opposite Theatre Royal. The auditorium is a flat-floored multi-purpose room, decent enough, but not Atkinson at his best. The 1999-2000 works to the complex included radical improvements to the Dome and Pavilion Theatre."
