The town is notable for the huge self-contained structure containing apartments, stores, schools, bars, a hotel, restaurants, a supermarket and swimming pool; the large building shelters a community of smaller apartment buildings and homes on its leeward side. Popularly known as The Wall (Le Mur), the structure was designed to be a windscreen to the rest of the town. It permits residents (other than mine workers) to never leave the building during the long winter, which usually lasts about seven months.
