An Eye-Catching Planetarium

An Eye-Catching Planetarium

Located on a hilltop in Forest Park beside a major highway, the St. Louis Science Center Space Science Building, also known as the St. Louis Planetarium, is designed to be eye-catching from a distance.

The simple, sweeping curves of its thin concrete shell (no more than three-and-a-half-inches thick) form a perfect hyperbola in silhouette, expressing the building’s function while also suggesting the vast reaches of the universe and the excitement of space exploration.

Parabolic exterior walls also shield rooftop telescopes at night.
