Competition | Lumina Nova: Architectural Illumination of Prague Castle

Prague Castle is awaiting new illumination – beautiful, sustainable and technically outstanding. We are looking for a multidisciplinary team to design, deliver and install it with respect for the uniqueness of the site.

The existing architectural and public illumination of Prague Castle has served for a long time; however, from a technical perspective it no longer meets current possibilities and requirements. 

Technological progress in the field of light sources, optical systems and lighting control now offers solutions that are more energy-efficient, more flexible and more considerate of the historical context than was possible at the time the current system was implemented. At the same time, approaches to the nighttime image of cities and to the regulation of light pollution have also evolved. The brief therefore calls for a complete replacement (new construction) of the illumination system, which also makes it possible to propose a new lighting concept.
