Castillo de Santiago in Sanlúcar de Barrameda, in the province of Cádiz, rents its courtyards, terraces and halls for company events, presentations, congresses, concerts and celebrations. The largest space, the Patio de Armas, takes a seated banquet for 500 or a standing cocktail for 750. The Salón del Duque serves smaller groups, from 80 in classroom layout to 160 at a banquet.
Seminars and company events
The castle's events page lists presentations, company meetings, congresses, concerts and exhibitions among the uses. The Salón del Duque covers 194 m² and is the natural room for a seminar: 80 people in classroom layout or 120 in theatre layout. The Aula Maior (120 m²) and the ground floor of the Torre del Homenaje (50 m²) are covered rooms that suit smaller sessions or breakouts. Several projection and exhibition rooms, from 100 to 350 m², are also covered and can host plenary presentations or product launches.
The castle states that its facilities are fully air-conditioned, which helps for a daytime meeting in Andalusia in summer.
Weddings and receptions
The venue lists ceremonies and celebrations among the events it hosts. The open-air spaces are the obvious choice for a reception. The Patio de Armas covers about 1,110 m², is open to the sky and can take a marquee. The Barbacana de la Sirena (200 m²) and the Barbacana de Santiago (225 m²) are open rectangular terraces, useful for a drinks reception before a dinner in the courtyard or in the Salón del Duque.

History and setting
The House of Medina Sidonia built the fortress in the 15th century, and the castle has more than 500 years of history. It looks out to the sea, and the Torre del Homenaje gives views and an Atlantic breeze. The castle also houses a costume museum and an arms museum, included in general admission, which can give a group something to visit between sessions. It is an open monument with public opening hours, so event dates and times are agreed with the events coordinator.
Getting there
The castle stands on the Plaza del Castillo in Sanlúcar de Barrameda. The events team checks availability for the dates you have in mind.
