When Queen Victoria sold the Royal Pavilion Estate in 1850, the future of its buildings hung in the balance: there was a strong chance that the former royal stables would be demolished. After a successful petition, local government purchased the estate, securing its future in public ownership. This gave the building a new purpose, and it was transformed into a Concert Hall and Assembly Rooms: Brighton Dome as we know it now. Brighton Borough Surveyor Philip Lockwood oversaw the conversion, retaining the dramatic scale of the building while introducing a richly decorated Moorish interior, complete with stained-glass windows and a magnificent gas-powered chandelier. Around 3,000 people could be accommodated, seated on rows of cane chairs and wooden benches. The transformation and its lavish décor cost approximately £10,000, including £1,950 for a grand organ built by the London firm Willis & Co, widely regarded as one of the greatest British organ producers of the Victorian era. The venue opened with an inaugural concert on 5 June 1867.
