The city of Alcobaça became notable after the first king of Portugal, Afonso Henriques, decided to build there a church to celebrate the conquest of Santarém to the Moors, in 1147. The church later evolved into the Monastery of Alcobaça, one of the most magnificent gothic monuments in the country. In the church are the tombs of King Peter I and his murdered mistress Inês de Castro. Over the centuries this monastery had an important role on Portuguese culture.

A few kilometers to the north of Alcobaça is located the Abbey of Batalha, another wondrous gothic building constructed in memory of a different important battle, that of Aljubarrota. To the west of Alcobaça is the well-known fishing village of Nazaré. To the south is Caldas da Rainha and the quaint medieval town of Óbidos that is an attraction for any tourists that enjoys a true glimpse of the past. Also to the south is the town of Porto de Mós with its fanciful rebuilt castle.
