Lausanne is the capital and largest city of the Swiss French speaking canton of Vaud. It is a hilly city situated on the shores of Lake Geneva, about halfway between the Jura Mountains and the Alps, and facing the French town of Evian-les-Bains across the lake. The municipality of Lausanne has a population of about 140,000, making it the fourth largest city in Switzerland after Basel, Geneva, and Zurich, with the entire agglomeration area having about 420,000 inhabitants Initially a Celtic and Roman settlement on the shores of the lake, Lausanne became a town at the foot of Notre Dame, a cathedral built in the 12th century. In the 20th century, Lausanne became a focus of international sport, hosting the International Olympic Committee After the fall of the Roman Empire, insecurity forced the residents of Lausanne to move to its current centre, a hilly site that was easier to defend. From 888 to 1032, the initially relatively small town belonged to the kingdom of Upper Burgundy. During the 11th century, Lausanne developed into a political, economic and religious center It was invaded by forces from the canton of Bern and remained under their domination from 1536 to 1798. The iconoclastic Bernese stripped the Lausanne cathedral of its Roman Catholic trappings, and a number of its cultural treasures, including the hanging tapestries in the cathedral, were permanently removed.
