Hotel Arbez
Les Rousses, Switzerland
The Hotel Arbez, also called the Hôtel Arbez Franco-Suisse or L'Arbézie, is a hotel that straddles the international border between France and Switzerland in the tiny village of La Cure, which is itself divided by the boundary. Built by a private landowner and businessman specially to take advantage of an impending border adjustment between the two countries, the structure was originally used as a grocery store (its Swiss portion) and a pub (the French half). Today, the entire building houses a hotel, whose dining room, kitchen and several rooms are bisected by the boundary.
