The legacy of the Lord of Àger : Arnau Mir de Tost route

FlyAger Collegiata de San Pere
The Arnau Mir de Tost route is an authentic trip back through time to the 11th century when the Serra de Montsec served as a frontier between Muslim and Christian territories.
It was at that time that the Arnau Mir de Tost, a knight to the Count of Urgell, crossed this frontier and captured Àger from the Muslims, thereby extending the Christian-held territory towards the south.
He achieved quite spectacular feats during the course of the border conflicts however it was his marriage to Arsenda, daughter of the lord of Montanisell, that enabled him to become a successful military leader, not only due to the economic resources to which he had access, but also due to her social network that he exploited to the full. The purchase of Llordà Castle in 1033 ensured his dominance of the Tremp river basin, where he also acquired the other important fortifications Orcau, Toulon and Mur.
Once he had established his control over these lands, Arnau Mir de Tost focused on a new target: the Andalusian (Muslim) controlled territories to the south of the Montsec range, of which the powerful fortified position of Àger was the cornerstone of the Andalucian government.
Àger was taken by the troops of Mir of Tost in 1034, upon which Count Urgell appointed him master of the newly conquered population, and he devoted himself to the reorganization and repopulation of the seized territories in the region of Montsec. Over the next decade, this stronghold of Àger changed hands several times between Muslim & Christian control until 1047 when Àger definitely fell into the hands of the Christians.
To the west, he expanded beyond the natural frontier of the river Noguera Ribagorçana and extended his dominion as far as the river Éssera. This meant that in the decade of 1060, he controlled the valleys of the Segre and the two Nogueras, and even collected taxes from the taifas of Lleida and Saragossa.

In 1064, Arnau Mir of Tost played a decisive role in the conquest of Barbastre, the first important Muslim city to fall into the hands of a Catalan feudal army. When Ermengol III died in battle, Arnau Mir acted as governor of the county of Urgell together with the viscount of Castellbò. He died in 1072 during a pilgrimage to Santiago de Compostela in Galicia.

As well as his leading role in the border conquests, Arnau Mir of Tost was responsible for extensive construction and left behind a legacy of architectural heritage that still characterises the area today: the castles of Llordà, Mur and Lluçà and the Collegiate Church of Àger are the most important examples.
