Cerisy-Gailly became Cerisy is a
commune whose origin is very ancient. The village existed before the founding of the
abbey of Corbie in the 7th century. It was one of the first donations made to the
abbey which had installed a
priory and a
provost to control the exploitation of the land. The
seignior of Cerisy was from the
castle of
Bray-sur-Somme. A communal
charter was granted to Cerisy in 1159 and the
parish was created in 1220. In the 15th century, Cerisy was ravaged by the
Burgundians as a stone engraved in the portal of the church indicates. On 4 August 1636 the
Spaniards crossed the Somme at Cerisy, unable to do so at Bray. In 1693, a school was founded in Cerisy. At the
Revolution, the
priory was suppressed and from 1870–1871 the population had to undergo the requisitions of the
Prussian army. From
1914 to 1918, the village saw a large number of troops gathering on the way to the marching up down the
front line. On 1 January 1966 the town then known as Gailly became a
hamlet of
Sailly-Laurette of which it is separated only by the
Somme and Gailly took the name of Cerisy. By a prefectoral order of 27 December 2016, the commune was detached on 1 January 2017 from the arrondissement of Péronne to integrate the arrondissement of Amiens. The
mayor is Claudie Duthoit, re-elected in 2020. ==Notable people==
