PIX4569347: Sundial - Invalides - Paris - Sundial in Paris - Hotel des Invalides: The sundials of the western facade of the monument of the Hotel des Invalides. Here, the first dial of the afternoon. It indicates the Babylonic hours (the number of hours elapsed since sunrise) and signs of the zodiac. In the court of honour, the hour was given on each facade: to the north, by a clock and on the other three facades, by seven solar dials. If the clock is missing, the dials are still visible / Bridgeman Images
