The well-conserved modern city has been rationally designed, and contains quarters and buildings with clearly defined functions and significant visual and architectural qualities. The modern city is characterised by the coherence of its public spaces and by the putting into practice of public health ideas (services, role of vegetation, etc.). The city includes a full range of monumental, architectural and decorative elements from the various earlier dynasties. The modern city of Rabat tangibly expresses a pioneering approach to town-planning, which has been careful to preserve historic monuments and traditional housing. Criterion (ii): Through its urban ensemble, its monuments and its public spaces, the modern city of Rabat shows respect for, and draws inspiration from, the earlier Arabo-Muslim heritage.
