40 Years UNESCO World Heritage Trier — Light Installation Konstantin Basilica

The Konstantin Basilica (Latin "Aula Palatina") was built around 310 as the audience hall of the imperial palace. With an interior length of 67 meters, a width of 27 meters, and a height of 33 meters, it was one of the largest interior spaces of Roman antiquity — and remains the largest preserved column-free space from Roman times to this day. Since 1856, it has served the Protestant community of Trier as a church; together with the other Roman buildings of Trier, it was declared a UNESCO World Heritage Site in 1986.

This extraordinary architecture forms the stage for the opening light installation of the 2026 World Heritage Anniversary Year. Trier light artist Manfred “Ollie” Olma — known for large-scale laser light spaces in historic buildings — is creating a walk-in sound and light space that makes the ancient architecture newly experienceable through contemporary light settings. Geometric laser projections, atmospheric soundscapes, and a live organ improvisation on the Konstantin Basilica organ combine to create a multi-sensory overall impression.

In front of the Basilica, a winter outdoor lounge with standing tables, mulled wine, and snacks will be set up, where visitors can linger before and after the performance. The event is family-friendly and free of charge.
