| At night this laser, that shoots out alone the Prime Meridian, it can be seen for miles around Greenwich. Here the light defuses on the wall around its exit point. | Paintings inside the observatory. Unfortunately the windows (either side of the paintings) that the telescopes were meant to poke out of were found to be several degrees out of alignment. This meant the astronomers had to do all their work outside in the cold! | Keep your eye on the ball! In the age of sail the time ball at Greenwich was very important for navigation. It was used to tell the ships exactly what time it was by dropping on the hour. |
