Here is a video to give you an overview of Portugal:
The video above shows the lifestyle of the Portuguese, as well as the pride the Portuguese have for their country. From the video, you can see the culture of the Portuguese as well, such as sports, religion, music, arts and literature.
Population
Portugal has around 10.7 million inhabitants. Its growth rate is rather small with an estimated 0.27% in 2009. The Portuguese population has its origin in several different peoples that settled in Portugal in historic times, such as the Celts and Germanic tribes. However, these ethnic groups have blended over the centuries and the Portuguese are today fairly homogeneous.
Sports
Football (Soccer) is not a game in Portugal; it is a national obsession. Although mostly a spectator sport, football is also regularly played by many Portuguese at weekends. No matter where you are in Portugal, people gather for informal matches on Sunday afternoons at sport complexes or grassy fields on the outskirts of town.Life and often the national economy come to a near standstill during any big match, with bar and restaurant TVs showing nothing else. Post-match celebrations has become a tradition, with fans taking to the streets, honking, setting off fireworks and gridlocking entire town centres until the wee hours.
The country was consumed with football hysteria in 2004 when it hosted the UEFA European Football Championships, the biggest sports event ever staged in Portugal. For more on UEFA European Football Championships 2004, click here: http://euro2008.football-shirts.co.uk/euro2004.html
Bullfighting
Bullfighting is a traditional spectacle of Portugal. It was first recorded in Portugal a staggering 2000 years ago by a Roman historian. The sport was then honed in the 12th century, when the tourada became a way to maintain military fitness and prepare nobles for horseback battle.
A typical tourada (refer to picture above) starts with an enraged bull charging into the ring towards a cavaleiro, a dashing horsemen dressed in the 18th-century finery and plumed tricon hat. The cavaleiro seizes the animal up as his team of peões de brega (footmen) distract and provoke the bull with capes. Then with superb horsemanship, he gallops within inches of the bull's horns and plants several barbed bandarilha (spears) in the angry creature's neck.
At the second stage, eight brave young forcados challenge the bull directly without any protection or weapon of defense. The front man provokes the bull into a charge to perform a pega de cara or pega de caras (face catch). The front man secures the animal's head and is quickly aided by his fellows who surround and secure the animal until he is subdued.
Bullfighting remains popular here despite opposition from international animal-welfare organisations as Portugal's own anti-bullfighting lobby is vocal but small.
The season runs from late April or March to October. The most traditional contests take place in bull-breeding Ribatejo province, especially in Santarém during the June fair.
Religion
Portugal was profoundly Roman Catholic. According to common saying, "to be Portuguese is to be Catholic," and approximately 97 percent of the population considered itself Roman Catholic--the highest percentage in Western Europe.
The country is famous for its impressive pilgrimages and romarias (religious festivals in honour of a plethora of parton saints), which continue unabated and are celebrated with a special fervour in the north.
The picture above shows one of Europe's most important centres of pilgrimage in Portugal at Fátima, where up to 300,000 pilgrims congregate every May and October. Days before the popular pilgrimages on the 13th of each month from May to October, the roads to Fátima will be crowded with thousands of pilgrims who walk to the sanctuary from all over Portugal. These people come to pay vows, pray or ask the Virgin for help.
During the last night of every pilgrimage cycle, the large square in front of the basilica turns into a sea of light, as tens of thousands of pilgrims hold up candles while attending outdoor mass. For more information on Fátima, click here: http://www.sacredsites.com/europe/portugal/fatima.htm
Arts & Literature
Portuguese literature has long been moulded by foreign influences but has retained its individuality throughout. Two major styles dominate: lyric poetry and realistic fiction.
Monument of Luís Vaz de Camões, Lisbon
The country's most outstanding literary figure is Luís Vaz de Camões (1524-80), a poet who enjoyed little fame or fortune in his lifetime. Only after his death was his genius recognised, thanks largely to a poem, Os Lusiadas (The Lusiads; 1572)
It tells of Vasco da Gama's 1497 sea voyage to India, but it is also a superbly lyrical paean to the Portuguese spirit, written when Portugal was still one of the most powerful countries in the Western world. Four centuries after its humble publication, it is considered the national epic, its poet a national hero.
Other famous poets includes Almeida Garrett (1799-1854), José Maria de Eça de Queirós, Fernanda Pessoa (1888-1935) and José Cardoso Pires(1925-98).
Today, Portugal's literary scene is largely dominated by two people: José Saramago and António Lobo Antunes.
Music
Fundamental to Portugal's history of musical expression is its foot-tapping folk music, which you can almost hear at every festival. It traces its roots to the medieval troubadour and is traditionally accompanied by a band of guitars, violins, clarinets, harmonicas and various wooden percussion instruments.
Of all the folkloric music traditions, fado is the music that best expresses the Portuguese sentiments of nostalgia and saudade. The fado, which means 'fate' in Portuguese, is a ballad about the tribulations of life, lost love, about saudades and aspects of Lisbon's low life of old.
The video below is fado music by Amalia Rodrigues, who brought fado international recognition. Enjoy!
Food
Although Portugal is a small country, it has a richly varied cuisine. Every religion, and sometimes every town, has meat dishes, stews, soups, desserts and pastries is truly astounding. Portugal's characteristic dishes are hearty and reveal a traditional skill of creating satisfying and tasty meals with simple ingredients.
Bacalhau
Bacalhau (dried, salted cod) is the food item most associated with Portuguese cuisine. It is prepared in every possible and imaginable way, from simply grilled to steamed, cooked in milk and made into fried patties.
Arroz de marisco
Portugal also has an amazing variety of seafood dishes, such as the Arroz de marisco (seafood rice)[picture above] which is a seasoned stew made with several types of seafood and cooked together with rice, and the cataplana (refer to picture below), a traditional dish of steamed seafood from the Algarve. 
Cataplana
In addition to the great variety of seafood dishes, Portugal also has a rich selection of meat dishes with great regional variations. One of the most popular Portuguese beef dishes is Bife à portuguesa (grilled beef steak topped with a fried egg) and Cozido à portuguesa (a stew made with cabbage and meats such as pork, chicken and smoked sausage) is considered be some to be Portugal's national dish.
A number of sweet dishes are prepared seasonally for special occasions. Among them are rabanadas (made from white bread soaked in sugar syrup, then dipped in beaten eggs and fried which is popular in the Minho region at Christmas), filhos (a type of fritters which is also popular during Christmas), and the Folar de Páscoa (a sweet bread baked with whole eggs inside which is popular at Easter)
