A massive and colourful pneumatic structure sweeps down on the NTCH Main Plaza. 

Inspired by nature, geometric shapes, as well as Islamic and Gothic architecture, Katena was created by the UK-based company Architects of Air. Time's engravings gave colour to architecture; light and shadows left their marks on spaces.

Katena takes its name from the catenary curve - the characteristic shape of a suspended chain, such as was used by Gaudi to design the Sagrada Familia. More than 100 catenary curves are found inKatena. The first catenary encounter is in the airlock where the windows have the form of an inverted catenary. Entering the Green Dome the catenary appears as a motif generated by displaced seams. The spectacular Main Dome of Katena has been likened to a Hindu temple. Its construction widened the boundaries of our pneumatic explorations with an intricate mesh of riveted and sewn reinforcement defining the shape and over 200 colour spots swirling upward to a green finial.

This is a place of serenity for all to explore and experience in every way. We cordially invite you to join us for a journey in Katena, to enjoy the shimmering beauty of colour and light.
