摘要：Geodiversity and geoheritage, which is the base to the establishment of Geotourism routes, are best preserved in rural areas (where natural heritage was not yet destroyed by human intervention). However, many urban areas have preserved quite interesting examples of geoheritage. Urban geoheritage can and must be known and promoted, by setting up geotourism routes for national and foreign visitors. The value that these geotourism routes add to the common tourist guides may represent a precious asset to a segment of tourists increasingly interested on the integration of natural heritage and other types of heritage, and may contribute to the growth of national tourism industry. In this paper the basic conceptualization it will best set and applied to Lisbon Metropolitan Area and, as a still preliminary approach, to the Lisbon city itself.
