Wanna show you very good piece of architecture - a finalist of this year's competition (category new and old) - Shopping Center Renoma in Wroclaw (link)
Renoma Department Store (at first called Wertheim) was built in 1930 by Wertheim Family, and was a part of large department store chain (Renoma is the last existing part). The author of the project was german architect Hermann Dernburg. He designed seven-floor building in modernist style, with rounded edges and big windows.
