Cultural assets should be freely accessible to all. And for this reason, the city of Valencia has constructed "The City of the Arts and Sciences" on its eastern outskirts.
The immense space is divided by one street into two areas which are interconnected via a common central axis. The smaller area houses The Palace of the Arts, exhibiting every type of art. The Science Museum and Planetarium are located on the other larger area. All the buildings are surrounded by water and are accessible via an axial footbridge.
The Planetarium is situated concentrically on the connecting axis between the museum complexes. It has an enclosed hemispheric dome made of reinforced concrete, and under this the circular auditorium is located. It is surrounded by an outer filigree shell which can be opened by means of a movable metal construction.
