The UFRGS Astronomical Observatory (OA) appears in the historical context of the transfer of the Porto Alegre School of Engineering, in 1899, to the location that currently houses the UFRGS Central Campus, with strong influences from positivism. On September 18, 1906, the Astronomical and Meteorological Institute (Instituto Astronômico e Meteorológico, IAM) was founded as part of the School of Engineering, being inaugurated on January 24, 1908 by the President of the State of Rio Grande do Sul, Dr. Antônio Augusto Borges de Medeiros (1863--1961).
At the end of 1908, the Observatory began to have in its four floors, 1909, the Workshop, the Secretariat Section, the Meridian Room with Time Service and the Equatorial Room with dome.
The Astronomical Observatory forms a set of three small buildings together with the Château and the Castelinho, which contrast with the neighboring buildings of the same period (Engineering, Law, Instituto Júlio de Castilhos), of large dimensions.

This building is an emblematic work of the scientific emphasis of the Brazilian architect Manoel Barbosa Assumpção Itaqui (1876--1945), director of the Astronomical Observatory and professor at the engineering school. He also erected several other buildings of the current central campus from UFRGS.

Only a few observatories exists in Art Nouveau style -- here with a mixture of eclecticism and classicism -- with an aesthetic balance of evident influence of contemporary Belgian architecture -- the Observatório Central da UFRGS (Instituto Astronômico e Meteorológico, IAM) for astronomy and meteorology, in Porto Alegre, Rio Grande do Sul, Brazil (1908), restoration in 2002 (cf. Granato, in: Wolfschmidt 2009, p.~130--131).

Since its origin, the Astronomical Observatory had the vocation to provide services to the community, among them, the Hora Certa Service (timekeeping) and the implementation of meteorological stations in the State of Rio Grande do Sul, in addition to Field Astronomy and Geodesy classes for Engineering students. The UFRGS was created in 1934 and until the 1960s the main task was the training of qualified engineers in geodesy.

In addition, other activities were: measurements of magnetic declination across the state, meteorological services and bulletins, seismography, observation of double and variable stars, determination of the height of the pole (latitude) of Porto Alegre and photographic record of comets, planets and aspects of the Moon. The Observatory was responsible for decades for the monthly publication of the Astronomical Ephemerides, including the map of the sky, in the traditional newspaper from Rio Grande do Sul, O Correio do Povo.

In 1942, the part of Meteorology was federalized, leaving to the OA the didactic activities related to Astronomy.
In the 1940s, the Morro Santana Observatory (OMS) was inaugurated with the aim of developing research in Astrophysics.

In the University Reform implemented in 1969/70, Astronomy was grouped with Physics, and the OA/UFRGS became an auxiliary body of the Institute of Physics (IF) of UFRGS with the name that remains until the day of today: Astronomical Observatory of UFRGS (OA). In 1971, the Physics Department and the Department of Astronomy merged and it was decided to build a stellar photometer (initially with the support of the Observatory of La Plata in Argentina).

The Observatório Central da UFRGS (Instituto Astronômico e Meteorológico, IAM), Porto Alegre, is recognized by the Instituto do Patrimônio Histórico e Artístico Nacional (IPHAN): <i>"Itaqui’s eclecticism mixes vague references to classicism with art noveau characteristics, which demonstrate its familiarity with an architecture style suggested at the time in Europe and non-existent in the capital of Rio Grande do Sul."</i>
In August 2002, the historic building, listed by the <i>National Historical and Artistic Heritage Institute</i> (IPHAN), was handed over to society, restored.

Over the years, with technological changes, the OA has lost its primary functions. Currently, it develops activities aimed at the community, such as guided tours of the museum, sky observation and workshops, offered to schools and the general public.

The Observatório Central da UFRGS is no longer used for astronomical research, but for astronomy outreach. The UFRGS Astronomical Observatory, an auxiliary body of the Institute of Physics, aims to promote development, education and social inclusion through astronomy and related sciences, using research, formal and non-formal teaching and extension activities, in addition to to rescue and preserve the memory of Astronomy in Rio Grande do Sul. Among the services offered to the population are observation of the night sky and guided tours of the collection, available to schools, by appointment, and to the general public.
In the 2000s, the Campus do Vale Observatory (OCV) was created in order to meet the didactic demands of the Department of Astronomy.
