Avenue Foch is the widest road in Paris. It is also one of the most prestigious, exclusive avenues in the capital. Opened in 1854 by Napoleon III, it was constructed to link the Champs-Élysées and the Bois de Boulogne. It has the unique feature of having gardens and unpaved bridle paths running along each side. The district surrounds this road lined with plush, Haussmann-style buildings, home mainly to well-off families, celebrities, and retirees. Made up of luxury residences and mansions, the Foch district is relatively quiet.
