The complex was established in 1970 to commemorate the centennial of the first Argentine National Observatory.
The planetarium uses a projection dome that covers 360 degrees of the audience's field of vision.
The Museo Experimental de Ciencias located within the complex is dedicated to interactive physical science rather than traditional artifact displays.
The observatory is equipped with professional-grade telescopes that are occasionally opened to the public for specific solar or lunar events.
The Municipal Astronomic Complex (Complejo Astronómico Municipal) in Rosario is a specialized scientific facility integrated into the Urquiza Park landscape. It houses the Planetarium of Rosario, an observatory, and the experimental space museum known as the Museo Experimental de Ciencias. The planetarium features a central projector system capable of simulating the night sky for educational shows. The facility serves as a primary center for astronomy outreach, hosting regular sky-watching events and celestial navigation workshops. Its architecture is specifically designed to minimize local light interference while remaining within the city limits. The complex functions as both an academic site and a public engagement venue focused on physics and space exploration. Educational programming is tailored for school groups, though it remains open to the general public for independent exploration.
