Palacio de los Duques Gran Meliá in Madrid hosts seminars, company receptions, private dinners and weddings. The largest setting, the combined Palacio + Opera hall, holds up to 250 people. Six event rooms, a 1,000 m² garden for outdoor events and a rooftop with a pool complete the offer. The hotel occupies a 19th-century palace with an Isabeline facade at Cuesta de Santo Domingo 5 and 7, between Plaza de Oriente and Gran Vía, in the Madrid de los Austrias district.
Seminars and company events
The hotel presents its event offer as a set of rooms with natural light, a garden and a rooftop, all in one building in the center of Madrid. The six rooms run from a 34 m² space for 16 people to a combined hall of 340 m² for 250. For a board meeting or a workshop, La Fragua (16 people), Las Meninas (40) and Las Lanzas (50) suit small and mid-sized groups. For a plenary session, a product presentation or a client reception, Opera (140) and Palacio (160) offer larger floor areas, and the two can be joined as Palacio + Opera.
The hotel states that its events team designs each event to order. It also takes part in the Road to Net Zero Events programme, which measures the emissions linked to accommodation, meeting rooms and catering. The organiser receives the figures in the proposal and again at the end of the group, and can offset the footprint through the company's own program or leave it to Meliá Hotels International.
Weddings and receptions
The hotel sells weddings and says each one is personalized in every detail. Ceremonies and receptions can use the indoor halls, the 1,000 m² garden or the rooftop. For a wedding dinner indoors, Palacio + Opera is the largest option at 250 people. Smaller celebrations fit in Palacio (160) or Opera (140).
