Main Room at PROUD CITY

Three hundred standing or 235 seated in a recently refurbished underground club beneath the City of London’s financial district. The Main Room at PROUD CITY — designated CITY1 — centres on a large dance floor surrounded by luxurious booth seating, all directed towards a sizeable stage backed by a huge screen. The refurbishment replaced the venue’s original speakeasy styling with a modern urban jungle aesthetic — opulent, stylish, and designed for both high-energy party nights and polished corporate events. The underground setting creates an intimate, contained atmosphere despite the substantial capacity.

Production and Technical Capability in PROUD CITY’s Main Room

The stage and screen combination is the room’s defining feature for corporate event planners. A full lighting rig, PA system with professional sound equipment, and in-house technical support create genuine presentation and performance capability — awards ceremonies can run formal presentations followed by live entertainment without any rig changes. The huge screen handles visual content, branding, and live feeds. State-of-the-art sound and lighting throughout the room mean the technical infrastructure matches dedicated event spaces rather than feeling like a nightclub with a projector bolted on. Removable floor tables clear the dance floor area for events prioritising movement and energy. The luxurious booth seating around the perimeter provides VIP areas and guest seating without separate furniture hire.

Events That Work in PROUD CITY’s Main Room

Awards ceremonies and corporate dinners are a strong fit — the stage, screen, lighting, and AV handle the formal presentation element, while the underground club atmosphere and entertainment capability mean the same room transitions naturally into a celebration once proceedings conclude. The booth seating gives awards events built-in VIP areas, and the removable floor tables create a dancefloor-ready layout for the after-party without guests waiting through a furniture changeover. Corporate Christmas parties and private birthday parties benefit from the contained energy that underground venues generate — the low ceilings, booth lighting, and enclosed space create an intensity that large open rooms struggle to replicate. Product launches gain visual impact from the production rig and the atmospheric setting, with the stage and screen handling keynote presentations and the surrounding booths providing a natural networking layout for post-launch reception. Late-night events have genuine runway — the alcohol licence runs until 3am with extensions available, which is rare for City of London venues and a meaningful advantage for celebrations, Christmas parties, and corporate events where the programme extends beyond midnight. Cabaret, burlesque, and circus entertainment can be sourced through Proud’s established network of elite performers, giving event planners access to a curated entertainment programme without managing external bookings or separate supplier contracts. Daytime conferences and exhibitions use the room’s flat floor and AV capability in a completely different register — the space proves surprisingly effective as a presentation room when the party lighting gives way to the screen, stage, and sound system operating in corporate mode. Film shoots find a controllable underground space with professional lighting infrastructure already in place.

PROUD CITY Main Room — Connection to CITY2 and Location

CITY1 connects to the newly refurbished CITY2 — a smaller room with its own raised DJ booth, banquette seating, and small stage. Both rooms have private entrances, bars, cloakrooms, and toilet facilities, meaning they operate independently or combine for 600 total capacity. For larger events, CITY2 serves as a second room, VIP area, or contrasting space within the same venue. For smaller corporate events, sit-down dinners, or informal gatherings, CITY2 works as a standalone hire. The venue sits at 1 Mark Lane, a short walk from Tower Hill tube and Fenchurch Street station. The City location makes it accessible for corporate audiences in the financial district, while the underground entrance means guests step out of the City’s commercial streetscape and into something entirely different. In-house catering handles bespoke menus including three-course fine dining, with lift access available.
