The eye of the complex
Designed by Santiago Calatrava, L'Hemisfèric opened on April 16, 1998 as the first public building in the Ciutat de les Arts i les Ciències. Its roof stretches more than 100 m (328 ft), the surrounding pond covers about 24,000 m² (258,334 ft²), and the whole composition is meant to read like a giant human eye. Even before you enter, it feels theatrical.
Why the dome feels different
Inside, the projection room holds more than 300 people and uses a 900 m² (9,688 ft²), 24 m (79 ft) concave screen. IMAX Dome, digital 2D/3D, and full-dome systems make the room feel more enveloping than a standard cinema, especially with astronomy or nature content. This is the main reason the stop punches above its size.
Programming keeps it fresh
Official CAC updates show how actively the venue refreshes its lineup: a 2025 full-dome launch, recurring live planetarium sessions, and a 2026 program still mixing astronomy, nature spectacle, and family-friendly stories. If you have already been once, the smart move is to check the current show list first and return when a new topic really pulls you in.
