The Sun into the Duomo of Florence

The Sun inside the Duomo

The Sun inside the Duomo

Yesterday the sun passed through the Gnomone and lighted up a part of the Duomo.

This is a peculiar astronomical event that happens every year just for a few days between may and July and for a few minutes around noon. This year it happened yesterday and again on Thursday June 21st and 28th on a certain time between 12.30pm and 1.30.

The Gnomone is a particular astronomical instrument that was built in 1475 by Paolo Dal Pozzo Toscanelli. It is the largest on its kind in the world and allows to measure the exact position of the sun thanks to its shadow. The sun light hits the Duomo’s ground for a few seconds inside the Cross Chapel, near the main altar where there are a thin brass meridian enclosed into two marble circles onto the floor. The major circles measures 90 cm that is the largest sun shadow of the Summer solstice.

The event is free for a maximum of 150 people. The entrance is through the Canonici Door right in front of via della Canonica for the next Thursdays in June at lunch time. I strongly recommend you see this peculiarity of Florence!

  1. ciao valentina,

    how early do you think one needs to join the queue for this event tomorrow?

    thanks for your reply!

    • Ciao svm! I would say you should be there at least 30 minutes before, since only 150 people are accepted. The entrance is at 12.30pm so you be there not later than 12pm if you want to get in. I would love to see your pictures if you’d like to share them. Enjoy it!
