摘要：Through field work campaigns and with the colaboration of several public entities, were identified several outcrops in Lisbon city. Nineten of them were classified as Geomonuments. In consequence they were included in Municipal Planning Instruments, its acessibility and visibility was assured and description totems were developed. Involving the general public was the strategie adopted in order to proceed with the dissemination and preservation strategies. In urban areas is not expectable to find references of evolution and earth dynamics, mainly because of the general tendency that promotes the total ocupation of the ground with construction. However, in Lisbon it is still possible to observe some outcrops preserved among buildings and roads, some of them with large dimensions that materialize several geological formations since Cretaceous to Holocene Periods. The original paleoenvironments associated to the lithostratigraphic diversity presented in Lisbon area, leads to a great potentiality of the city aiming the preservation and dissemination of the geological heritage. The Lisbon Municipality, in cooperation with the MNHN (Nacional Natural History Museum), the Lisbon University and LNEG (Laboratório Nacional de Energia e Geologia – the portuguese institute with functions similar to a Geological Survey), developed field work campaigns aiming the inventory of the preserved outcrops in Lisbon city, with scientific, educational and cultural interest, liable to be classified as Geomonuments. After the classification of those outcrops, some projects were developed aiming the preservation and maintenance of those places and some dissemination strategies such as the development of thematic trails to general public and schools.
