Why people search for Nus
Two reasons: the Aosta Valley regional astronomical observatory at Saint-Barthélemy, in the hamlet of Lignan — one of Italy's best dark-sky sites — and the proximity of the Castello di Fénis, one of the most photographed castles in the Alps.
The observatory
Run by the Fondazione Clément Fillietroz-ONLUS and inaugurated in 2003, at Lignan about 14-15 km up the mountain from the Nus exit on the A5. It has a planetarium under a 10-metre dome. Visits are by reservation only.
Getting there
Nus is on the Aosta-Pont-Saint-Martin line, about 13 km from Aosta, and Arriva runs buses along the same corridor. Note that the Aosta Valley railway has been undergoing works and replacement buses may operate. Reaching the observatory itself without a car means a taxi from Nus.
In the village
Nus also has its own castle, the Castello di Nus (Castello di Plane), reached on foot through the vineyards.
