Bad Elster celebrated a special anniversary in 2018: 170 years as official Royal Saxon Spa. For this occasion, the NaturTheater received a complete refurbishment. During the festive opening on the 8th of June, the 1,535 new seats of the EHEIM model ARC LITE PLUS in RAL 3004 purple red were unveiled to the enthusiastic audience. The Chursächsische Veranstaltungs GmbH was a constructive and competent partner from the first sample presentation until the final installation.
