The city of Stadthagen is a cultural centre in the district of Schaumburg. The lighting master plan is intended to enhance the quality of stay in the evening and night hours in a sustainable manner. For this purpose, practical and functional aspects of outdoor lighting in the city centre will be investigated and new lighting criteria will be established. On this basis, a lighting concept will be developed that harmonises the aesthetic aspects of urban lighting with the needs for public safety, functionality and recreation. As a first step towards the implementation of the concept, the illumination of seven historic buildings was planned and realized.
