Architects of Air’s 22nd luminarium is dedicated to the theme of ‘trees’.

In Arboria evidence of trees is to be found in forms and in graphic representation. The visitor first encounters one of the three 8 metre high domes, each one dominated by a single colour - red, green or blue. Each dome bears its own stylised leaf motif rendered in graphic simplicity to fit the underlying shape of a stellated dodecahedron.

Travelling on the visitor will arrive at the first substantial tree – a combination of cones and spheres that give rise to a brightly luminous tree trunk and branches that reach over their head.

There are three of these tree-like structures that triangulate the magnificent main dome. This 10 metre high dome takes its inspiration from the Chapter House of York Minster and one can see an interpretation of the original tall Gothic windows and the arching columns that culminate in radiant rib vaulting.

Arboria's sound experience originated in the Ecuadorian Cloud Forest where musician and soundscape ecologist, Alice Eldridge (, made recordings for biodiversity monitoring. To the forest and wildlife sounds Alice has added her own piano composition.
