Laisonnay is the oldest and most remote hamlet. It was here that the first inhabitants (of Haute-Tarentaise) settled, after crossing the Palet Pass into the valley. It contains a dozen or so stone buildings with traditional stone slate and wooden shingle roofs and a renovated with smattering of more recent materials. Houses are grouped together in order to make use of the few locations not exposed to natural risks (avalanches, rock falls and flooding by the Doron). Notre Dame des Neiges Chapel downstream of the hamlet and the old oven upstream are both well worth a visit.
