Toulouse sits on the banks of the River Garonne in France's south western region of Haute Garonne, almost equidistant between the Atlantic Ocean and the Mediterranean Sea. The city was founded as Tolosa, a Roman Military outpost, and is now a thriving modern metropolis home to over 400,000 people, as well as being the capital of the Midi-Pyrenees region. Rent a car from Toulouse Blagnac Airport and explore the city's vivid pink stone architecture, which has resulted in the nickname 'La Ville Rose'. Visit the 11th century Basilique St-Sernin church, which is instantly noted for its spectacular spire. Some of the most spectacular local buildings are the opulent mansions, a reminder of the city's wealthy merchant history, which are dotted around the Old Town.
