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.
Estoril
The Estoril coast is relatively close to Lisbon, the Portuguese capital; it extends from Carcavelos, from the capital, and stretches as far as the beach of Guincho (sometimes referred colloquially as the "Costa de Estoril-Sintra" or "Costa de Lisboa"). Estoril includes several smaller boroughs and localities along the coastline, namely (from east to west): São Pedro do Estoril, São João do Estoril, Santo António do Estoril (or simply Estoril) and Monte Estoril, as well as other to the interior.
