Owing to its easy accessibility, its elevated position on a terrace with a broad sky to the west, south, and east and low light pollution, the place offers ideal conditions for observing celestial bodies.

The municipal council recognized that the construction of an observatory could be a big gain for the village, since no similar investment had been made in the Grisons by that time.

On 11 September 2002, a working group was created and the architectural firm of Schneider & Cathomas from Falera took over the planning of the observatory.

The restaurant space is also used for introduction to the observatory and bad weather programs as an alternative to star gazing.

It has a mirror diameter of 90 cm (35 in) and 2.7 m (9 ft) focal length, and is one of the largest publicly accessible telescopes in Europe.

The observatory of Falera, together with the ones of Winterthur, Carona and Ependes is one of the stations that observe asteroids, comets and satellites and measure their pathways.

The data are sent to the Minor Planet Center of the International Astronomical Union at Harvard University and from there to NASA.

The asteroid "Falera" was discovered on 21 November 2009 by the founder of the observatory José de Queiroz.

With the naming, the work of the Observatory Mirasteilas is recognized, which deals with the discovery and orbit determination of unknown minor planets since 2008.
