The country of Portugal is surrounded by the Atlantic Ocean on its western and southern sides; however, it shares the Iberian Peninsula with the country of Spain. Portugal inhabitants enjoy the sunny climate and relaxed lifestyles that make many visitors want to enjoy the alluring towns and villages alongside them.
While Portugal is a part of modern Europe, it’s a rural nation that’s been able to stand the test of time with many flourishing traditions. Modern high-rise resorts have lined the coast in the southern province of Algarve along with all the makings for a great vacation package. Portugal’s capital Lisbon is situated on the country’s west coast and it’s bustling with many resorts for tourists to enjoy. If visitors head north or east, they’ll discover an area that’s primarily stunning countryside but with many different medieval villages and towns where life hasn’t changed much since the centuries in which they were established.
Portugal inhabitants have a close attraction to water as many of its mariners, famous and not so famous, have made explorations to Africa and the Americas. They’ve even begun trade routes to countries in the east. Up until the 20th century, Portugal was a strong colonial power; afterwards, outsiders heavily influenced the country both on its culture and architecture. For instance, the African maudlin fado music is a unique experience for visitors especially for Lisbon cafés.
