The Queen Mary Undercroft sits within the Old Royal Naval College and offers exclusive hire for daytime and evening events. The space features majestic columns, a high vaulted ceiling, and a dancefloor, making it suitable for corporate gatherings, receptions, conferences and celebrations. The venue can accommodate larger numbers and benefits from access to the Colonnades outside for weather-permitting gatherings. A Victorian Skittle Alley is available for guest entertainment. The Undercroft can be hired individually or alongside other spaces within the building, including the Painted Hall for combined events.
