Lisbon (1956 film)
"Lisbon" was entirely produced in the Portuguese capital city of Lisbon and its surrounding municipalities. It was considered the first Hollywood feature made in Portugal. For interior shots, the production used the facilities at Tobis Studios. Exterior shots included many locations in Lisbon, among them the Belém Tower, Praça do Comércio, the Castle of São Jorge and the Jerónimos Monastery. Outside the capital, there were seaside scenes filmed in Cascais and a scene at the belvedere of the Seteais Palace, in Sintra.
Lusitanian Basin
The Lusitanian Basin is located on both mainland and continental shelf of the west-central coast of Portugal. It covers a 20,000 km area and extends from south of Lisbon, the capitol of Portugal, to Porto. This north-south oriented Atlantic margin rift basin is approximately 130 km wide and 340 km long and belongs to a family of periatlantic basins such as the Jeanne d'Arc Basin. To the east of the Lusitanian Basin lies the Central Plateau of the Iberian Peninsula and a marginal horst system lies to the west. The Alentejo and Algarve Basins connect to the southern end of the Lusitanian Basin. In the north, it is connected to both the Porto and Galicia Basins via a basement ridge.
