The Pla d'Almatà archaeological site constitutes the city of Balaguer's original nucleus. In the 8th century, Arab and Berber troops established a military settlement in this enclave as they followed the Segre River on their path towards conquering Europe. Pla d'Almatà is an archaeological site which would come to form the centre atop which the present-day city of Balaguer was established. In the beginning, during the 7th century, it was founded as a military camp by Saracen troops. Under the Upper March's rule, it would become a city: madina Balaguer.
The Pla d'Almatà lends the chance to view an archaeological park in which four large houses and a section of the street have been excavated and turned into a museum, along with remains of the 8th century wall.
