Buhl Planetarium and Institute of Popular Science Building

Buhl Planetarium is a science education center in Pittsburgh's Allegheny Center featuring a distinctive octagonal copper dome and multiple exhibition spaces. The structure houses historical projection equipment and mechanical demonstrations that show visitors fundamental scientific concepts.

The planetarium opened in 1939 and was one of the first public buildings with air conditioning, highlighting its pioneering technology. After operating as a science museum for decades, it later transformed into a family-focused learning center.

The building represents Pittsburgh's commitment to sharing science with the public and draws visitors interested in exploring the cosmos. Its halls serve families seeking hands-on learning experiences together.

The location sits in central Pittsburgh and is easily accessible by public transportation. Visitors should plan time to explore the exhibition areas, as there is much to discover inside.

The building once housed a Zeiss projector, a sophisticated German device that displayed thousands of stars on the dome ceiling. This technology was groundbreaking for planetarium engineering of its era.
