Lisbon is the capital and the largest city of Portugal, with an estimated population of 505,000. It is mainland Europe's westernmost capital city and the only one along the Atlantic coast. Lisbon lies in the western Iberian Peninsula on the Atlantic Ocean and the River Tagus. The westernmost portions of its metro area form the westernmost point of Continental Europe, which is known as Cabo da Roca, located in the Sintra Mountains.
The city of Lisbon is rich in architecture; Romanesque, Gothic, Manueline, Baroque, Modern and Postmodern constructions can be found all over Lisbon. The city is also crossed by historical boulevards and monuments along the main thoroughfares, particularly in the upper districts; notable among these are the Avenida da Liberdade (Avenue of Liberty), Avenida Fontes Pereira de Melo, Avenida Almirante Reis and Avenida da República (Avenue of the Republic).
Lisbon is home to numerous prominent museums and art collections, from all around the world. The National Museum of Ancient Art, which has one of the largest art collections in the world, and the National Coach Museum, which has the world's largest collection of royal coaches and carriages, are the two most visited museums in the city. Other notable national museums include the National Museum of Archaeology, the Museum of Lisbon, the National Azulejo Museum, the National Museum of Contemporary Art, and the National Museum of Natural History & Science.
Prominent private museums and galleries include the Gulbenkian Museum (run by the Calouste Gulbenkian Foundation, one of the wealthiest foundations in the world), which houses one of the largest private collections of antiquaries and art in the world, the Berardo Collection Museum, which houses the private collection of Portuguese billionaire Joe Berardo, the Museum of Art, Architecture and Technology, and the Museum of the Orient. Other popular museums include the Electricity Museum, the Ephemeral Museum, the Museu da Água, and the Museu Benfica, among many others.
Lisbon's Opera House, the Teatro Nacional de São Carlos, hosts a relatively active cultural agenda, mainly in autumn and winter. Other important theatres and musical houses are the Centro Cultural de Belém, the Teatro Nacional D. Maria II, the Gulbenkian Foundation, and the Teatro Camões.
The monument to Christ the King (Cristo-Rei) stands on the southern bank of the Tagus River, in Almada. With open arms, overlooking the whole city, it resembles the Corcovado monument in Rio de Janeiro, and was built after World War II, as a memorial of thanksgiving for Portugal's being spared the horrors and destruction of the war.
13 June is Lisbon´s holiday in honour of the city's saint, Anthony of Lisbon (Portuguese: Santo António). Saint Anthony, also known as Saint Anthony of Padua, was a wealthy Portuguese bohemian who was canonised and made Doctor of the Church after a life preaching to the poor. Although Lisbon’s patron saint is Saint Vincent of Saragossa, whose remains are housed in the Sé Cathedral, there are no festivities associated with this saint.
Eduardo VII Park, the second largest park in the city following the Parque Florestal de Monsanto (Monsanto Forest Park), extends down the main avenue (Avenida da Liberdade), with many flowering plants and greenspaces, that includes the permanent collection of subtropical and tropical plants in the winter garden (Portuguese: Estufa Fria). Originally named Parque da Liberdade, it was renamed in honour of Edward VII of England who visited Lisbon in 1903.
Lisbon has two sites listed by UNESCO as a World Heritage Site: Belém Tower and Jerónimos Monastery. Furthermore, in 1994, Lisbon was the European Capital of Culture and, in 1998, organised the Expo '98 (1998 Lisbon World Exposition).
