 note = {Applying spatial analytical methods to Christaller's (1933) original data, this paper re-examines the spatial arrangement of central places of the L-system of Munich. The results show that central places were not so hexagonally located as was predicted by central-place theory. The marked gap between the theory and its verification may have occurred because (1) his keen recognition of the German circumstances of the time requiring a national land planning theory, (2) his inductive discovery of the spatial order of medieval towns, and (3) his sense of place for southern Germany perhaps let Christaller to look at the region with a theory-ladden eye and to conclude prematurely that the theory was confirmed.},
