One must start with the history of the Portuguese people themselves. They discovered most of the "new world", and did so by trading rather than violence.
The country and Europe's most southern point. A narrow land with beautiful golden beaches stretching the whole length of the country.
Some of the best wines in the world; so good that the Portuguese drink most of it themselves!
The food which varies from region to region, with black pig from the Alentejo, fresh fish from the Atlantic and a cod dish for everyday of the year.
Fado music, touches your heart and soul.
The warmth of the people, family values and a smile for the visitor.
Architecture, narrow alley's, the hustle and bustle of a night on the town.
Everyone's interests are different, my recommendation would be to come and see for yourself.
