Fabra Observatory
Astronomers here still hunt asteroids and comets through the same Paris-built telescope the observatory opened with in 1904.

The fourth-oldest still-functioning observatory anywhere, doing live research with century-old optics rather than sitting behind glass as a relic.
What to look for
- The 1904 Mailhat double refractor from Paris: two tubes on one mount, a 38 cm visual scope at 6 m focal length beside a shorter 4 m photographic one.
- The Baker-Nunn Schmidt camera beside the antique refractor.
- Where Josep Comas Sola discovered comet 32P/Comas Sola, which now carries his name.
Perched 415 m above Barcelona; an active research site of the Royal Academy of Science and Arts (obs. code 006), not a general-admission museum.
Fabra Observatory is one of 39 sights worth the detour in Barcelona, all bundled offline in Voyage GO — download the Barcelona pack and it sits on your map with no signal, filling your travel passport the moment you walk past.
