Historical Background
The building got its name from the round glass structure that crowned the spacious ground-floor hall and opened onto the enclosed inner courtyard. No later than 1911, a branch of Nathan Sternfeld's Königsberg department store opened in this building at 39 Königsberger Strasse. Above the front door hung a sign with the owner's name. As shop windows should, they displayed the finest goods to lure tourists. The authors of an advertising “Guide” were generous with their praise for Nathan Sternfeld's store.
