Huly Hill is a 30 metre diameter earthen burial mound, surrounded by a modern retaining wall. At its highest it is around 3 metres. The mound was excavated in 1830 and a dagger or spearhead was found along with some cremated bones. Around the mound are three standing stones; two are around 2 metres tall, and the third is probably broken and stands 1.2m tall. The cairn and the stones were in use at different times. The monument may date from around 2500 BCE.
The remains of an Iron Age chariot burial were found near mound. The chariot was the first of its kind to be found in Scotland and shows Iron Age Scotland in direct contact with the European Continent. The Newbridge chariot was buried intact, a method consistent with the burial practices of Continental Europe rather than Yorkshire.
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.
