Bordeaux is the capital of the Aquitaine Region and the administrative seat of the department of the Gironde. Situated in the south west of France the Gironde is surrounded on three sides by the other departments of Landes, Lot et Garonne, Dordogne and Charente-Maritime.
The west of Gironde is coastal and flanked by the Atlantic Ocean. It is the largest department in metropolitan France with an area in excess of 10,000 squared kilometres.
The city of Bordeaux is built on the river Garonne which is wide enough and deep enough for merchant freight ships and even ocean liners to travel along in order to dock in Bordeaux. The rivers of the Garonne and the Dordogne merge and flow together out to the Atlantic along the channel known as the Gironde estuary.
