The first inhabited centre that you come to when going up the Valle del Lys road, it is situated at an altitude of 655 metres.
The origin of the name comes from the Latin “Insule Haelianae”, from the ancient name of the river Lys.
An attractive stone bridge, the only one with four arches in the Valle d’Aosta, built in 1733, links up the two slopes. The bridge leads to the parish church of San Rocco, a building dating back to the early 1600’s and whose adjacent bell tower is from the 1400’s, but was raised two centuries later.
A French-provencal dialect with strong Piedmontese inflection is spoken in Lillianes as well as in Perloz and Fontainemore.
Immersed in thick, vast chestnut trees, the river Lys runs through the town.
>From Medieval times, to the end of the XVIII century, Lillianes links its history to that of the Vallaise lords.
A vast heritage stemming from the coexistence and harmonious combination of important historical remains, environmental resources still intact and thriving traditions and culture are all to be found in Lillianes.
The cultivation of chestnut trees so typical of this area with its excellent production both from a qualitative and quantitative point of view, is an example of this heritage.
There are numerous possibilities for excursions in search of naturalistic points of interest: the Bec Fourà (1830m) whose summit is literally “perforated” and the Plan des Sorcières (1800 m), where you can view remains of ancient witchcraft rites.
