Castillo de Arteaga can host weddings, celebrations, business lunches and private gatherings for up to 230 guests in its great dining hall, and up to 280 when the space is extended. The castle is a hotel and restaurant in Gautegiz Arteaga, in the province of Bizkaia in the Basque Country.
Seminars and company events
The castle presents itself for personal or professional meetings, wine tastings and sit-down meals, in interior spaces and outdoors. The official site does not describe a dedicated meeting room, screens or a seminar package, so a company event here is best framed as a lunch, a dinner or a reception with a speaking slot. Ask the team what audiovisual equipment and break-out space they can provide before you commit to a program.
The restaurant, Gaztelu Maitea, is also offered for business lunches. An aperitif or a post-meal coffee can be served in the lounge that comes before the dining room, which gives a small group a separate place to gather.
Weddings and receptions
The castle promotes itself for weddings and celebrations, built around its large dining hall. The venue states a capacity of 230 people, extendable to 280, and describes the setting as adaptable to the needs of each group. The surrounding countryside allows activities indoors and outdoors, so a ceremony, cocktail and dinner can be planned across more than one space.
Rooms and capacities
The main figure to plan around is the dining hall: 230 seated guests, up to 280 with the extension. The restaurant dining room and the lounge in front of it handle smaller occasions, such as a private lunch or an aperitif. The site gives no separate capacity for these two rooms.
Accommodation
The hotel offers seven room categories: double, double for single use, standard with terrace, Junior Suite Newman, Suite Maria Eugenia, Suite Lazkano and Junior Suite Napoleon. Standard rooms are in the main building or on the ground floor of the wall towers, with original stone or wood walls, and one is adapted for guests with reduced mobility. The terrace room and the Junior Suites are in a wall tower reached by internal stairs, which the hotel does not recommend for guests with mobility problems. The two suites in the main building have a sitting room and views over the countryside and the Urdaibai biosphere, and are accessible. The site does not state the total number of bedrooms, so confirm how many your group needs before fixing a date.
Catering
Catering is handled by the castle's own restaurant, Gaztelu Maitea, which serves an a la carte menu, set menus and tasting menus. The kitchen describes its cooking as high cuisine. The castle also has a winery section on its site, and wine tastings are among the events it lists.
History and setting
The castle was remodeled by Empress Maria Eugenia de Montijo. Ornamental and decorative elements remain, and the hotel combines period furniture with contemporary pieces. The grounds are a natural setting in the Urdaibai area.
Getting there
The address is Gaztelubide Kalea 7, 48314 Gautegiz Arteaga, Bizkaia. The official site does not give transport details, so ask the hotel about parking, shuttle options and the best way to arrive from Bilbao.
