It's in Santa Maria de Alcobaça Church that the love between D. Pedro and D. Inês de Castro rests. The history of this monument, though, began well before that, about ten years after the foundation of Portugal, which makes it the oldest of the four World Heritage Sites in the centre of Portugal.

Originally known and founded as the Monastery of Santa Maria da Vitória, the Monastery of Batalha, a UNESCO World Heritage Site since 1983, is a proof of devotion and gratitude of D. João I for the victory in the Battle of Aljubarrota, which assured him the throne and guaranteed independence for Portugal.

For almost seven centuries since its foundation, the University of Coimbra has played an absolute unquestionable central role on the production and transmission of knowledge worldwide and also in the formation and unity of the Portuguese language. For its outstanding and exceptional value, the University of Coimbra, Alta and Sofia is listed as a UNESCO World Heritage since June 2013.

The Templar Castle and the Convent of Christ in Tomar is one of the largest monumental complexes of peninsular and European architectures, either in space as in time. Its very unique synthesis of both the old and new worlds of the Discoveries through the Manueline style justified the classification of this site, in 1983, as UNESCO World Heritage Site.
