Portugal

Officially called the Portuguese Republic, Portugal is a country on the Iberian Peninsula. Located in southwestern Europe, it is the westernmost country of mainland Europe and is bordered by the Atlantic Ocean to the west and south and by Spain to the north and east. The Atlantic archipelagos of the Azores and Madeira are also part of Portugal.

Portugal is one of the warmest European countries and enjoys a Mediterranean type climate in the south and a Koppen type climate in the north. The northern landscape is mountainous in the interior areas, with plateaus indented by river valleys. The south, between the Tagus and the Algarve, features mostly plains and a climate somewhat warmer and drier than in the cooler and rainier north. The Algarve, separated from the Alentejo by mountains, has a climate much like southern coastal Spain. Portugal's highest point is Mount Pico on Pico Island in the Azores. This is an ancient volcano measuring 2,350 meters (7,713 ft). Mainland Portugal's highest point is Serra da Estrela, measuring 1993 meters (6,558 ft).
