As a canonical it already existed in the year 891, because its archdeacon and clergy were present at the consecration of the church of Sant Andreu de Baltarga. In the act of consecration of Santa Maria d'Urgell in the 9th century, it is mentioned first and mentioning the churches and villages that belonged to it. In the 10th century, Bishop Sisebut gave it to the church of La Seu d'Urgell. La Cerdanya always formed a pagus or demarcation of the bishopric of Urgell. Talló, mentioned in some documents as the "pagus Tollonensis", heads the list of parishes in Cerdanya, in the Act of Consecration of the Seu d'Urgell dated 839. The deanery organization was erected by Bishop Guillem de Montcada, a Dominican, in 1299. Each deanery had a dignitary or dean who looked after the rectors of the parishes in his territory, represented them and exercised over them a jurisdiction delegated by the bishop. The first dean of the Archdiocese of Cerdanya was Raimon de Morer, who also acted as a representative of the king of Mallorca, with the title of "ardiachonus Certanie" as his tombstone reminds us. During his term of office, the original church of Talló was expanded, turning it into the current Collegiate Church. In the place of Talló, in the last decade of the 11th century, an Augustinian canonry had been established, which remained until the 14th century. There is a donation from Count Ramon Guifré de Cerdanya in 1098. The archdeacon of Cerdanya, a canonical dignity of the Seu d'Urgell, had resided there. The sanctuary dedicated to the Virgin Mary of Talló is a suffragan of the parish of Bellver.

Prat de Cadí, an ancient lake of glacial origin filled with sediments, now converted into a majestic meadow at the foot of the north face of the Cadí mountain range. Access by the Estana - Prat de Cadí - Canal del Cristall route: The total length of the route is 12 km, with an elevation gain of 1,100 m, and the journey requires approximately 5 hours for the ascent and descent. The excursion begins in Martinet, an area where the granite base of the axial Pyrenees is visible, and continues upwards along the road to Estana. Along this path, the route traverses the entire sequence of pre-Hercynian Devonian rocks, which have been displaced southward during the movement of the Cadí mantle. Travelers must pass through the village of Estana and park their vehicle at the Pallers pass parking area, situated at the edge of the natural park. By car, part of the significant elevation difference between the Cerdanya plain and the Cadí ridge is already overcome; this topographical transition mainly results from the subsidence of Cerdanya roughly 10 million years ago during the Miocene, which was shaped by a complex fault system.
