Popular around Barrage Du Crescent
Crescent Lake owes its name to its crescent shape. It is popular with local fishermen and also with swimmers who can visit its beach to cool off. Camping is also permitted. This lake, with its exceptionally bucolic setting, was chosen as the location in 2015 by Michel Gondry for filming his movie Microbe and Gazoil.

There is no possibility of touring the lake by mountain bike along the banks, but rather by taking the road. However, check that the road that passes over the dam is open (temporarily closed until June 25, 2025 for us!).

The second part of the village's name comes from the large number of empty stone tombs placed in the cemetery surrounding the church. The church is the central location of the village, next to the mayor and not far from a mini-market and a few shops.

The Crescent Dam was built between 1929 and 1932. A gravity dam, it is 330 meters long and 37 meters high. Its width at the base is 24 meters and at the crest 3.5 meters. It was built on the initiative of SA Compagnie HydroElectrique de la Cure and was owned by the City of Paris until 1946. The dam was built to regulate the waters of the Yonne and Seine rivers and thus prevent flooding in Paris, while also producing electricity. More than 165 hectares of cultivated land, hamlets, mills, and paths were flooded to allow the creation of the reservoir (maximum depth of 40 meters). It occupies four municipalities and two departments, and is fed by the Cure and Chalaux rivers. The structure was partly financed by war reparations owed by Germany to France after the First World War. This is why much of the dam's mechanisms are German-made. The road across it is narrow and only allows passage for one vehicle. Fortunately, there is very little traffic.

Straddling the departments of Nièvre and Yonne, with an area of 138 ha, Lac du Crescent owes its name to its "crescent" shape. This lake is formed by a hydroelectric dam built in 1930 and financed as German war damage linked to the 1st World War. The dam is 330 m long, 37 m high and the capacity of the lake is 14 million m3. The Crescent reservoir is fed by the most famous trout rivers in the Morvan: the Cure and the Chalaux. It is therefore a good fishing spot, like all the neighboring lakes of the Morvan, but a swimming area has also been set up on the side of the Yonne in the town of Chastellux sur Cure.
