The Alentejo region covers almost the entire lower third of Portugal. It is an agricultural area with many grain fields that have been feeding the country since the Middle Ages. Historically, the Alentejo was the most important route to Portugal from Spain, and the many medieval castles show that the relationship between the two nations was not always friendly. The capital of the Alentejo is Évora, a beautiful UNESCO World Heritage Site surrounded by medieval walls and hidden Roman ruins. The Alentejo is one of the most varied regions of Portugal. On the western coastline it is possible to surf on nearby deserted beaches while in the east old fortified towns are waiting to be explored. In between are empty roads, olive fields, and sleepy villages - the Alentejo is the idyllic heart of Portugal.
