Planetario Municipal Agrimensor Germán Barbato, Astronomical science center in Montevideo, Uruguay

The facility is an astronomical observation center with a domed theater seating around 157 people for live presentations. Advanced projection technology creates detailed views of stars, planets, and celestial events across the night sky.

The planetarium opened on February 11, 1955, making it the first of its kind in Latin America and the southern hemisphere. This achievement reflected growing interest in bringing scientific education to the wider public.

The facility honors a local surveyor through its name and serves as a gathering place for people curious about the cosmos. It has become part of how residents in the city engage with science and learning about space.

The dome theatre, the Galileo Galilei hall, seats 157 to 239 people depending on the source, so arriving early helps on school-visit days. The planetarium receives over 500 schools and 100 lyceums a year and holds more than 1,000 shows between February and November. The Science Alive museum in the basement opens between May and November. The library on space topics is one of the most complete in Uruguay.

The Spitz Model B projector installed for the 1955 opening was still running in 2016, when it was described as the oldest working projector of its kind. It was retired during the 2017–2019 renovation and replaced by a digital system when the planetarium reopened in December 2019.
