The Round Room at the Mansion House hosts conferences, gala dinners, award ceremonies, charity lunches, product launches, hybrid events and Christmas parties for 250 to 500 guests. The circular hall stands on Dawson Street, Dublin 2, a few minutes on foot from Grafton Street and St Stephen's Green.
Seminars and company events
For conferences, the room seats up to 500 delegates in theatre style and up to 350 in cabaret at round tables, and classroom layouts are also possible. In-house audiovisual equipment is included in the hire. Integrated AV, staging and lighting come through the venue's partners, CAVs for production and High Res Lighting for event lighting, and the team adds branding, event design and entertainment on request. A dedicated event manager coordinates catering and suppliers. Gala dinners and award ceremonies take up to 500 guests, and reception-style events with food stations and entertainment zones also go up to 500. The venue recently put €250,000 into new lighting, sound and video equipment.
Rooms and capacities
The Round Room is a single circular space under a domed ceiling lit with stars, the Starry Dome, upgraded in 2019. It works as an open floor that can be styled from scratch, with branding throughout. The Lord Mayor's Supper Room, restored in the 1990s, is now home to FIRE Steakhouse and Bar. Exact banquet capacities depend on the layout and are confirmed by the team.
Catering
Catering comes from With Taste, the venue's partner, for banquets, canapé receptions and charity lunches. Menus are built for each event with the event manager.
History and setting
The architect John Semple built the room in 1821 to welcome King George IV, and it was first called the King's Room. Semple compared it to the circular courtyard of an Arabian palace, taking the Royal Pavilion in Brighton as a model. In 1868 the Lord Mayor gave a ball here for the Prince and Princess of Wales, with about 1,200 guests across the Round Room and the Oak Room. On January 21, 1919, the First Dáil Éireann met in the room. It later hosted ceremonies of the 1932 Eucharistic Congress, motor exhibitions in 1936 and 1959, céilís and community events. EHL Experiences took over the lease of the public rooms in 2005 and has since spent more than €2.5 million on restoration, including a €2.25 million upgrade of AV and lighting in 2015. The venue marked its bicentenary in 2021.
