The B. M. Birla Planetarium occupies the campus of the Periyar Science and Technology Centre at Kotturpuram, alongside eight exhibition galleries covering physical science, electronics, energy, life science, innovation, transport, international dolls, and materials science. Over 500 exhibits span the compound.
History
Completed in 1988, the planetarium was built as a memorial to B. M. Birla, the industrialist and visionary who shaped modern India’s scientific infrastructure. It stands as the fifth B. M. Birla planetarium established across the country, reflecting the family’s sustained commitment to public science education and cultural advancement.
What you see
The planetarium’s signature feature is its specially perforated hemispherical aluminium inner dome, engineered to project immersive cosmic shows. The architecture prioritizes technical sophistication—each perforation calculated to distribute light and imagery with precision. The surrounding science centre campus integrates galleries seamlessly, creating a cohesive environment for exploration and discovery.
Cultural significance
The planetarium represents India’s post-independence investment in scientific literacy and public engagement with astronomy. It anchors a broader network of Birla-funded institutions—including planetariums in Kolkata, Hyderabad, Tiruchirapalli, and Coimbatore—that democratized access to the cosmos for millions of visitors. The facility remains considered among the nation’s most modern astronomical venues.
