passagen
Passagen is the plural form of the German noun die Passage, and is used generally to refer to enclosed or semi-enclosed urban passages that house shops and other facilities—often glass-roofed arcades. In architectural and urban-history contexts, passagen describe nineteenth- and early twentieth-century shopping galleries that connected streets and offered sheltered pedestrian routes within city centers. They emerged in many European cities as commercial and social spaces, contributing to street life while providing climate protection and a unified retail environment. The design often combined architectural ornament with retail variety, creating a corridor-like public space used for strolling, meeting, and shopping.
In cultural history, the concept of the passagen/arcade has been used as a focal point for discussions
