The Starlight Foundation, linked to UNESCO, has granted the Montsec mountain range the international certificate of Starlight Tourist Destination > and also the Starlight Reserve.

The Mas de Bruquet is also part of the group of StarLight Monitors of Montsec, the objective is to help disseminate knowledge of astronomy through the sky of Montsec.

The Starlight Initiative is conceived as an international campaign in defense of the quality of the night skies and the general right to stargazing, as the scientific, cultural and environmental heritage of humanity.

The aim is to reinforce the importance that clean night skies have for humanity.

Starlight Tourist Destinations are visitable places that have excellent qualities for contemplating the starry skies and practicing tourist activities based on this resource.

The Starlight Reserve is a space where a commitment is established to defend the quality of the night sky and access to starlight.

The Starlight Tourism Certification System was created with the objective of promoting, worldwide, the improvement of the quality of tourist experiences and the protection of the night skies in Starlight Destinations.

The Starlight Certification allows for the first time to combine science and tourism, based on astronomy and the vision of the sky, a new form of intelligent tourism.

The Montsec Astronomical Park, which consists of the Observatory and the Universe Orientation Center; It becomes the fourth area on the planet for exceptional astronomical observation.

The other locations are the Roque de los Muchachos observatories in the Canary Islands, Mauna Kea in the Hawaiian Islands and Aura, located in Coquimbo, Chile.


The Montsec Astronomical Park (PAM) is an initiative of the Government of Catalonia through the Montsec Consortium, with the aim of taking advantage of the skills and potential of the Montsec area to carry out research, training and dissemination. of science, especially astronomy.

The Montsec Astronomical Park (PAM) is located in the Montsec mountain range, halfway between the regions of La Noguera and Pallars Jussà. The PAM consists of two main elements: the Universe Observation Center (COU) and the Montsec Astronomical Observatory (OAdM).


The Universe Observation Center is a large recreational multi-space with the aim of becoming the reference center for the teaching and dissemination of astronomy and geology in Catalonia. The COU is located in the municipality of Àger. The COU is a link between the public and scientific knowledge, bringing the visitor closer to the exciting world of science and the discovery of the Montsec environment. Taking advantage of the characteristics of a unique place as a sky for the observation of the Universe integrated in a medium that allows us to know the evolution of the Earth from the geology of the mountains.
The COU consists of three main structures:

Central Building: Where the reception and administration, the permanent exhibition, the workshop classrooms, the computer room and other services are located.

The eye of Montsec: It is a unique installation in the entire State, being both a multimedia digital planetarium and a platform for live sky observation. Its 12 meter diameter dome and the front wall open completely, leaving the visitor under the spectacular Montsec sky.

The Telescope Park It is the space reserved for observing the sky, both at night and during the day. The Park is made up of two buildings with observation domes that contain two automatic telescopes, a coelostat for solar observation and a set of portable telescopes.


The Montsec Astronomical Observatory (OAdM) constitutes the scientific aspect of the Montsec Astronomical Park (PAM) and its purpose is basically research and university training in the field of astronomy and astrophysics.

The OAdM is located in the municipality of Sant Esteve de la Sarga (Pallars Jussà), east of the Corona del Montsec d’Ares peak, 1570 meters above sea level. The OAdM consists of an observation building, a services building and a 6.15 meter diameter dome that contains the Joan Oró Telescope.
