Palacio Neptuno hosts corporate dinners, cocktail receptions, gala evenings, concerts and immersive events, in four spaces of 180 to 600 square meters. The building stands at calle Cervantes 42, in central Madrid, between Plaza de Neptuno and the Museo del Prado. The site does not publish guest capacities, so the figures below are surfaces.
Seminars and company events
The venue is run for business events. Its corporate team answers requests by email or phone and sends a quote within 24 hours, based on the number of people, type of event, dates, schedule, catering, audiovisual needs and set-up days. Site visits are arranged by phone.
Two formats set the place apart. The first is the candle-lit evening, staged with more than 1,500 candles, for gala dinners, concerts and premium cocktails. The second is the immersive event, with projection mapping on the walls, table mapping and a cocktail dinner built around live cooking. Both work for product presentations, client evenings and awards nights.
Rooms and capacities
Sala Venus, on the street level, is the main and largest room. It covers 600 square meters and rises to 12 meters under the central dome.
Sala Eunice, on the mezzanine, covers about 400 square meters. It connects to Sala Venus and looks over the inner courtyard, which makes it a good space for a reception before dinner or for breakout areas.
Sala Calipso, on the ground floor, covers 450 square meters and is reached directly from the street or from Sala Venus.
Terraza Neptuno, at attic level, is a rooftop terrace of 180 square meters with views over the district, with new lighting for evening use.
Floor plans are available as PDF and AutoCAD files on the official site, which helps production agencies plan staging. Ask the team for seated, banquet and standing figures for each room.
Catering
Only caterers approved by the venue may work at Palacio Neptuno. Medems Catering is presented as the official caterer, and the venue also promotes dinners by chef Ramón Freixa, who holds two Michelin stars. For other services, organisers may bring their own suppliers, except for those the venue marks as exclusive.
History and setting
The dome was built by Manuel Ortega. The palace sits in the Paseo del Prado and Buen Retiro area, inscribed by UNESCO as the Landscape of Light, a short walk from the Prado, the Thyssen-Bornemisza museum and the Neptune fountain. The venue holds the CO2 Responsables certification issued by Madrid City Council for venues that reduce emissions, and it publishes a sustainability policy.
Getting there
The palace is in the Barrio de las Letras, a few minutes on foot from Paseo del Prado. Atocha station, for high-speed trains, is about one kilometer south. The metro stations Antón Martín (line 1) and Banco de España (line 2) are within walking distance. Madrid-Barajas airport is about 30 minutes by road, depending on traffic. The street is in a dense central district, so plan coach drop-offs and load-in times with the venue team before the event day, and allow for set-up days in the quote.
