The Barthonia-Forum (called after the investor Barth) is a large mixed complex of habitations, space for trade and commerce and shops at ca. 40.000 qm, which earlier belonged to the administration and production of 4711, which took another location in the Ehrenfelder subdistrict Bickendorf in 1991. Barth transformed the older structures and used the 4711-colors gold and turquoise as stylish elements. The heart of the Forum is the mega-market Kaufland, good reachable by the Underground-tram Nr. 3 and Nr. 4 from the stations Körnerstr. and Piusstr..
