During medieval times, someone would climb the stairs of the Cathedral of Notre Dame every night to watch over the city of Lausanne, Switzerland, for approaching invaders or fires. The tradition of shouting out the all clear phrase “c’est le guet; il a sonnè l’heure” is still conducted hourly from 10:00 p.m. until 2:00 a.m. each night. This is their view. In the background are Lake Geneva and the Chablais mountain which is part of the Swiss Alps.
