Anna Science Centre, Science museum in Tiruchirappalli, India

Anna Science Centre is a science museum in Tiruchirappalli, on National Highway 210 between Trichy and Pudukottai next to Tiruchirapalli Airport. It was inaugurated on 10 June 1999 by the Government of Tamil Nadu. Its halls hold exhibitions and a 75-seat planetarium, a 3D theatre, an environment gallery and an Evolution Park.

The center was established in 1999 by the Tamil Nadu government as part of an effort to advance scientific knowledge in the region. Its founding reflected a commitment to making science education more available to the local population.

The center serves people from Tamil Nadu and beyond with programs that bridge language gaps and make science education available to all visitors. It plays an important role in how the region's residents learn about the natural world.

The center is open most days, with regular planetarium shows and guided tours available for visitors. It is best to allow several hours to explore the different halls and participate in the hands-on activities.

The Evolution Park covers 2 acres and holds models showing how species evolved. The centre also runs free sky-watch sessions where the public views celestial objects through a telescope, including during events such as eclipses. An Innovation Hub was being built at a cost of 2.25 crore to host workshops in scientific experimentation for school students.
