The Château des Boulard can host a seminar, a product launch, a trade show, a company Christmas party or a wedding for 10 to 500 guests. Business events use the Espace Grégoire, a 500 m² hall facing the château, while receptions and dinners take place in the salons of the château itself. The estate lies at Spoir, 6 rue du Moulin, in the commune of Mignières, near Chartres in the Eure-et-Loir.
Seminars and company events
The Espace Grégoire is the main room for professional events. It measures 500 m² and seats 500 in theatre layout or 400 at tables, with sound and video equipment included. The château, with 190 m² on the ground floor, is used alongside it for breakfast, coffee breaks, cocktails, lunch or breakout groups. The seminar package covers a welcome breakfast, a coffee break, lunch and hire of the equipped hall.
The hall also turns into a multipurpose space for casino evenings, giant-screen games, buffets or inflatables. The owners organise team activities inside the grounds, such as paintball, team building and a cardboard car-building challenge, called Carbox. The site lists Christmas trees for works councils, company anniversaries, New Year's Eve parties and car events among past uses. A lit car and coach park is on site. The owners offer drone video and a drone group photo of the day.
Weddings and receptions
For a wedding, the château offers its reception rooms and a round ballroom known as the rotunda. Inside the château, 120 guests can sit for lunch or dinner, and up to 450 can stand for a cocktail. With the other rooms of the property, a reception can reach 500 guests. A newer formula uses the château for the cocktail hour, with a fallback in case of rain, and the Espace Grégoire for the dinner and dance. The château is lit at night, and the park has fountains on the lake behind the house; a fireworks display can be added. During a wedding, children can be looked after in the Salle Pirate, a 500 m² room fitted out for them. Smaller family events can hire part of the château.

History and setting
The château, once known as the Château de Spoir, was built in 1768 for the lordship of Bérou and enlarged in the nineteenth century with two wings framing the original house. From 1953 it housed a public boarding school for children, then stood empty for 30 years. The Boulard family bought it as a ruin in 2004 and has restored it since, funding the work through weddings, seminars and public events. The 22-hectare park holds gardens, woodland and animals, including wallabies.
Getting there
The château is at 6 rue du Moulin, Spoir, 28630 Mignières, close to Chartres. The parking takes cars and coaches.
