Be amazed at the mysteries of space at Cagliari Observatory. There's so much waiting to be explored beyond our pale blue dot, from stars and black holes to rocky terrestrial planets.

This out-of-this-world attraction is often on the itineraries of travelers to Selargius. But Cagliari Observatory isn't the area's only highlight. Bastion of Saint Remy, National Archaeological Museum, and Roman Amphitheatre of Cagliari are some other interesting sights close by.

8.4/10 Very Good! (450 reviews)

The room was very clean, spacious, with very friendly staff. What I didn’t like was the fact they didn’t replenish the instant coffee in the room, having said that, the hotel does the job and the rates are reasonable.
