FIGURE 3

I ^C distribution over the network of places and connections; (1) the 'potential' network, where physical barriers are not considered; (2) the 'real' network, where barriers are considered. The real network (2) is fragmented in four disconnected sub-networks, each one with its own focal spot; all these 'local centres' do not form any organic system. The potential network (1) is a single connected system with one emergent centrality located near the cultural centre and the sport facilities. In all cases, the structure of places and that of paths (see Figure 4, col. 1) are not consistent, in that – as a general rule – marginal paths serve central places and central paths serve marginal places.
