Épernay’s handsome avenue de Champagne fizzes with maisons de champagne (Champagne houses). The boulevard is lined with mansions and neoclassical villas, rebuilt after WWI. Peek through wrought-iron gates at Moët’s private Hôtel Chandon , an early 19th-century pavilion-style residence set in landscaped gardens, which counts Wagner among its famous past guests. The haunted-looking Château Perrier , a redbrick mansion built in 1854 in neo-Louis XIII style, is aptly placed at number 13! The roundabout presents photo ops with its giant cork and bottle-top.
