Tomba dei giganti di Li Lolghi is a burial chamber which probably dates back to the period included between 1800-1200 BCE. Like the tomb of Coddu Vecchiu, it was built in two different phases for different uses: during the Nuragic Age the original Dolmen, high a bit less than 4m and probably belonging to the Bonannaro's culture, was linked to a 10m corridor made up by stones stuck in the ground vertically. This new passageway was the new burial chamber where the dead used to be put in through a small entrance at the bottom of the Dolmen.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
