[3] In May 1895 a farmer discovered a buried underground menhir weighing about three tons and about 3.4 m (11 ft) tall in Les Echâtelards.

The first Jura water correction of 1876 led to the drainage of a large part of the marshy field where the prehistoric village had been.

The Federal Archaeology and History Museum in Lausanne seized the opportunity and started excavations in the following year which dragged on until 1880.

Corcelettes is probably the one Swiss village that supplied the most metal objects from the Bronze Age to different museums and private collections around the world.

While it legally protected from looting, several thousand square meters of archaeologically important material has been lost due to erosion.

Several investigations of the, up to 0.6 m (2.0 ft) thick, artifact layers have found—not only pottery and some bronze objects, but also organic material (threads, bark, wood, leaves, seeds, etc.)

The findings from Corcelettes spread over the whole Bronze Age, but with a clear accumulation at the end of this period in the 9th century BC.

Some of the objects include; a small pig sculpture, a coil and terracotta horns, a flute and two sickle wooden handles, horse bits, three bronze vessels (including a basin in a northern Europe style), a broken brooch, a wheel made of ash wood, wheat bread, a bone plate made from pieces of about fifteen human skulls and a dugout canoe made of wood.

A copper bar, hammer, small tools and molds indicate that there was a metal processing and manufacturing shop in the village.

Either by 1146 or at least before 1178 the Grandson family supported the foundation of the Benedictine Priory of Saint-Jean, which belonged to the Abbey of La Chaise-Dieu in Auvergne.

The nearby villages of Provence, Bonvillars, Fiez, Concise and Yvonand were responsible for the maintenance of the walls.

Otto de Grandson, also spelled Otton, Othon or Otho (c. 1238–1328), was the most prominent of the Savoyard knights in the service of King Edward I of England.

In the village of Le Revelin, outside the city walls and close to the Giez gate, butcher shops opened.

Otto I promoted the mendicant orders and allowed the Franciscans to build a monastery at the western entrance of the town in 1289.

A hospital was built in the second half of the 14th century in today's Rue Basse, near the Gey gate tower, which was destroyed in 1837.

[5] In the late 15th century, Grandson castle belonged to Jacques de Savoie, an ally of Charles the Bold.

In late February 1476, Charles the Bold brought up a large mercenary army to retake the castle.

Swiss sources are unanimous in stating that the men only gave up when Charles assured them they would be spared.

When the main body of the Swiss emerged from a forest, the Burgundian army, already pulling back, became confused.

At insignificant cost to themselves, the Swiss had humiliated the greatest duke in Europe, defeated one of the most feared armies, and taken a most impressive amount of treasure.

The forerunners of the Protestant Reformation in Grandson included the coup of Guillaume Farel, who had destroyed the altars of the Franciscan church in 1531, and the sermons of the French priest Jean Le Comte.

In 1819, the Franciscan church and the cemetery were moved to Les Collombaires to allow an extension of the Rue Basse to the main road.

At the end of the 19th century, new docks were built along with magnificent houses on the new bank including the estate and astronomic observatory of the Vautier family.

[5] The income of the residents of Grandson came from agriculture, particularly from livestock raising on slopes of the Jura Mountains, but also from fishing.

The wine production was widespread in the late 19th century but decreased significantly with the emergence of parasitic diseases.

The wealthy Vautier family were closely involved in local politics and between 1899 and 1914, they held the mayor's office.

The automotive prototyping company Ateliers d'études de construction automobile Sàrl is headquartered in Grandson.

[6] Grandson lies at an elevation of 447 m (1,467 ft), at a distance of 3 km (1.9 mi) north of Yverdon-les-Bains.
