In the Haute-Garonne area of south-central France is the country's fourth largest city, Toulouse, home to over one and a quarter million people, over one hundred thousand of which attend the university, founded in 1229. The city has been a regional capital since the time of the Visigoths in the fifth century, and contains many buildings of architectural interest, some of which are built with the terracotta bricks that give the town the sobriquet 'The Pink City'. Today, Toulouse is home to the European Space Programme and the economy is reliant on the aeronautics industry and the businesses that support it; many of the Airbuses currently in operation were built in the city. Toulouse has a subtropical climate, so it can be humid. Summer temperatures hover around the high 70s Fahrenheit; in winter, it seldom falls below 40 degrees Fahrenheit. Toulouse-Matabiau is the main railway station; there is an unmanned metro and a comprehensive bus service operating. Local delicacies include the Toulouse sausage and cassoulet. There are two branches of Enterprise Rent-A-Car in Toulouse; Toulouse city and Toulouse Railway Station.
