The fence around De Nederlandsche Bank on the Frederiksplein is a true optical experience. While passing the building, a rhythmic, dynamic pattern appears and disappears in the trellis of the fence. The figures on the sides of the rails were designed in 1992 by artist Peter Struycken, a pioneer in the area of environmental art and generating computer-program based image, light and colour compositions.
The portal between the Leidseplein nightlife area and the Max Eeuweplein is pompously accentuated by a classical looking façade, designed in 1991 by Zaanen Spanjers Architects. On the frieze, supported by columns, the architect has carved an inscription: ‘Homo sapiens non urinat in ventum’ - ‘A wise man does not piss into the wind’. A ‘wisecrack’, disguised in Latin.
