1904 Fabra Observatory for study of asteroids and comets

About Fabra Observatory

The Fabra Observatory or Observatori Fabra was established in 1904 for the study of asteroids, comets and earthquakes. It is the fourth oldest observatory in the world that is still fully functioning. The observatory offers day guided tours and evening dinners, Dining with The Stars that include star gazing from the main Telescope.

Fabra Observatory History

Having decided to build an observatory at Tibidabo, in 1895 the Academy presented to the Provincial Council, a project drawn up by the architect Josep Doménech Estapá, with the scientific advice of Eduard Fontserè i Riba, an astrologist.

The attempt was frustrated due to competition with Tibidabo Temple for the prime spot on the top of tibidabo summit and a lack of funds.

Six years later, a gift from Camil Fabra y Fontanills, first Marquis of Alella, provided the appropriate funding, which was supplemented with financial support from the Provincial Council and Barcelona City Council.

The issue about location had been solved, the previous project was duly adapted by the same architect Josep Doménech Estapá, but now with the advice of the astronomer Josep Comas i Solà, both academics. The works began in 1902.

On April 7, 1904, the new Observatory was inaugurated, to which the Royal Academy, its owner, assigned the name of Fabra, in recognition of the patron who had made its construction possible.

You will get to view distant constellations, stars and much of the solar system from the telescope.

Accessibility, mobility & Clothing for Fabra Observatory

While no specific entry requirements, I only recommend taking a small rucksack or bag because the observatory staff will probably ask you to leave large bags, pushchairs and other bulky items on the ground floor while they take you on the guided tour.

Access between floors and to the roof terrace is only via stairs. The Telescope is on the second second floor inside the dome.

No bicycle anchorage outside or near to Fabra Observatory.
