Sardar Patel Planetarium, Planetarium in Sayaji Baug, Vadodara, India.

Sardar Patel Planetarium is a four-storey pyramid-shaped building in Sayajibaug, Vadodara, designed by P. S. Ranjan and Panna Ranjan with V. M. Shah as structural designer. Its sloping sides, clad in Kota stone, avoid the usual dome form; inside, a staircase links an open-air amphitheatre seating 300, a mezzanine, the planetarium chamber with a 12.5-metre dome and Zeiss Spacemaster projector, and a rooftop observatory.

The Vadodara Municipal Corporation built the planetarium near the main gate of Sayajibaug. Mohan Dharia, Minister of State for Works and Housing, laid the foundation on 3 November 1974, and H. N. Sethna, Chairman of the Atomic Energy Commission, inaugurated it on 12 July 1976. It was named after Sardar Vallabhbhai Patel for his birth centenary. After deterioration, it reopened on 24 October 2017 following a ₹6.03 crore renovation.

The planetarium is named after Sardar Vallabhbhai Patel, the independence activist, to mark his birth centenary. Shows run daily in Gujarati, Hindi and English, and special programmes are held on solar and lunar eclipse days and other astronomical events.

Plan your visit by checking show times in advance, as presentations run at different times throughout the day. The location within Sayaji Baug Park makes it accessible, with parking available nearby for those arriving by vehicle.

Beyond the planetarium itself, there is an attached science park displaying over 15 exhibits that demonstrate principles of physics and astronomy. This exhibition allows visitors to explore scientific concepts through interactive displays and hands-on engagement.
