The Sri Lanka Planetarium is a really cool place to learn about space and astronomy. The dome theater show is the highlight—relaxing, interesting, and a fun way to see the stars in a new way. The building has a unique design too, which makes it feel special.

Some parts could be updated, but overall it’s a great educational experience for students, families, or anyone curious about the universe. Worth a visit if you’re in Colombo with your kids.
