Astronomy in Palermo Cathedral

Summer is the best time to add an astronomical touch to your visit of Palermo's fascinating medieval Cathedral. In fact it is during the warmer months of the year that you can really observe the floor Meridian Line at work. During the colder months, the sunlight appears on it at noon, but is not very strong, and the disc of light on the Meridian is very quick in passing. During the summer months, thanks to daylight saving time,  LAN (local apparent noon) takes place around 1:00 PM. Due to clear summer skies, the effect of the disc of light on the colorful marble inlay zodiac signs is out of this world! Be sure not to miss this when visiting Palermo. It is a delight to see for adults and for children, and it definitely makes you ponder how quickly the earth is moving.
