We shall not cease from explorationAnd the end of all our exploringWill be to arrive where we startedAnd know the place for the first time.T.S. ELIOTIntroductionThink of Scotland. The chances are that what springs to mind is a picture of mountains, lochs, glens and coasts — an outstanding natural heritage which uplifts the spirit and overflows the pages of the tourist brochures. Paradoxically, though, modern Scotland has an urban heart, with its people, the lifeblood of its economy and its cultural centres all concentrated in the towns and cities. Scotland is fortunate in the quantity and quality of its historic towns, with a preponderance of small and medium-sized towns, many of which escaped the insensitive 1960s and 1970s redevelopment so eloquently lamented elsewhere. Even Scotland’s cities are small by English standards; the population of Glasgow, our largest city, was about 650,000 in the 1991 census, and Dundee, the smallest (before Inverness’s elevation), only about 165,000. Today some 80% of the total population of around 5,000,000 live and work in towns and cities.
