How to reach the Observatory

Daytime and Nighttime Visits
The entrance for the visits takes place only at the little gate on Via del Pian dei Giullari, 16
Since the street is narrow, it is not possible to stop or to park; it is suggested to stop in the wider part of the road between Via Torre del Gallo and Via Pian dei Giullari, easily reachable (also by bus) at the fork of Via del Giramontino, coming from Viale G. Galilei, both from the direction of Piazzale Michelangelo and from the direction of Porta Romana.
It is advised to be on time because, immediately after the group's entry, the gate will be closed and it will not be possible to enter at a time different from that scheduled.


General Information
It is recommended that the visitors adhere to the instructions given in the confirmation letter and/or in other communications.
In case of necessity (lateness, difficulty finding the entrance, etc.), the people responsible for the groups are kindly requested to contact by phone the staff at the Observatory, using the following numbers:
055 2752 227
055 2752 274
These numbers are enabled only at the time of visit, about 15 mins. before startof the visit; these numbers are to be considered in case of emergency.

Through the Astronomical Park

arcetriHow was the solar system made? How big are the planets? And, in what proportion are they to each other? How long does it take for light to reach a certain planet?
To these and to other fundamental questions, the Astronomical Park responds with scale model of the Solar System found in the grounds of the Observatory. Inaugurated in September 2009, in celebration of the International Year of Astronomy, and, thanks to the contribution of the Regione Toscana, the scale model of the Solar System was conceived by This email address is being protected from spambots.

Starting from the farthest of the eight planets, Neptune, located a little after the entrance to Arcetri, one arrives to Mercury, the closest planet to our Sun. The latter, located on the outer wall of the Amici Pavilion, concludes the walk in the open before entering into the dome to observe the sky with the telescope.
The planets are represented in their natural colors on iron structures capable of weathering the elements and of renewing itself with colors and alterations wich induce the strong visual and tactile impressions.
Mythology is the theme that is developed in the supporting structures of the planets: each planet evokes a myth and each myth becomes a simbol that characterizes each of the structures.
