Located in the heart of Parque Tres de Febrero (the famous Palermo Woods), the Galileo Galilei Planetarium is one of the most unique and iconic buildings in Buenos Aires. Its structure, shaped like a flying saucer or planet, is a gem of brutalist and futuristic architecture opened in 1966.

In addition to its striking silhouette reflected on the lake, its interior houses a state-of-the-art star projector, a domed main hall with 360° immersive projection, an astronomy museum, and real meteorite specimens.

In this guide, we cover how to book tickets, show schedules, what to see inside, and tips to make the most of your day in Palermo.
