O2 universum is a multifunctional cultural and congress centre in Prague, adjacent to the O2 Arena. The hall has four floors and a total area of almost 50,000 square metres. It can be used for exhibitions, corporate events, concerts, sporting events and more.

For the entrance lobby of O2 universum, Preciosa designed and installed a dynamic lighting installation that stretches more than 220 metres and is composed of 650 spheres. The hand-blown spheres are made from opal, bubbled, cracked, and frosted glass. Thanks to the atrium-like design of the lobby, the installation can also be seen up close from the first level. It took one year from design sketches to completion and one week to install it in the vast entrance hall. We were pleased to work with Czech-based architectural firm ATIP on this project.
