Château des Marais rents reception rooms and meeting spaces for 8 to 150 guests, and can be hired as a whole with bedrooms for up to 20 people. The château dates from 1755 and stands on a 12-hectare estate with a view over Lac de Grand Lieu, at Saint-Philbert-de-Grand-Lieu, 20 minutes from Nantes airport and 35 minutes from the Atlantic coast.
Seminars and company events
The château offers rooms for meetings, private or professional meals and receptions. Smaller groups use the rooms inside the château. Larger groups can use the park, where an equipped reception tent stands for more than 100 people, or a separate hall a short drive away. Outside caterers are accepted after approval by the management.
Before booking, ask which rooms are free on your date, since the château is also run as a hotel particulier with a wine cellar, an art gallery and a bar.
