Visiting the Observatory

Visits to the Vatican Observatory sites are constrained by our small staff and restricted quarters. Individual visits to the Observatory are not possible. 

Our telescope in Arizona is in a protected Forest Service area. Visits can be arranged through the Eastern Arizona College Discovery Park Campus:

Our offices and telescopes in Castel Gandolfo are in the Papal summer gardens. The Vatican Museum hosts tours of the Gardens and the former Summer Palace

At the moment these tours do not include visits to Specola sites; we are in the process of developing a Specola Visitor Center in conjunction with the Vatican Museums, and we hope to have this open to the public sometime in the coming year. Occasional visits by groups of 10-25 people can sometimes be arranged; enquire at
