The astronomical clock is renowned worldwide and is one of the attractions of Strasbourg Cathedral.

Every year, over 3 million tourists come to watch! Clocks are masterpieces of the Renaissance period, the result of collaboration between artists, mathematicians, and technicians. Clockmakers, sculptors, painters, and robot creators worked together. The current mechanism can be traced back to 1842. Clocks mainly attract people through the action of their automatic mechanism. The automatic mechanism works perfectly every day at 12:30. The astronomical clock demonstration takes place every day (except Sundays and holidays, when Mass is held at 11am). Enter the world of astronomical clocks, enjoy all aspects of its aesthetics, and marvel at the precision of the gears that make up its ingenious mechanism.
