Watch Lisboa de Hoje e de Amanhã (1948) Official Trailer

Recent population growth in the capital leads to an ambitious development plan, involving public and private initiative as documented here, pinpointing over 60 locations (streets, roads, parks, schools) being modernized or built anew. The narrative and soundtrack are grandiloquent, in the propaganda style required by the Producer (the Municipal Council of Lisbon, then directly dependent of the national government), but the images and data are now of historical relevance.
