With a privileged view over the sky to the South, the Museum of Lisbon – Roman Theatre is an excellent location to observe with telescopes the Moon, Jupiter and Saturn. This is also a chance for the whole family to learn more about the Universe.

On this Summer night, peek the meeting between Jupiter and the Moon from the terrace of the Museum of Lisbon – Roman Theatre. Through the telescopes, you will be able to take photos of these two celestial bodies that will be very close to each other in the sky.

It will be possible to see the craters and the “seas” on the Moon, and the planet Jupiter surrounded by its largest moons. Saturn, with its rings, will show up later in the evening.

Next, travel across the Solar System in the company of researchers of the Instituto de Astrofísica e Ciências do Espaço, exploring representations of the planets to scale, and, with the whole family, participating in activities about the Solar System.

Information, in Portuguese, also available at the Museu de Lisboa website.


  • The observations with telescopes are subject to good weather conditions, which may be known only on the same day after 2pm.
  • Free entrance, subject in every moment to the capacity of the museum.
  • Recommended to children aged 3 or above.
