Oisemont is a commune in the Somme department in Hauts-de-France in northern France.
Oisemont is situated on the junction of the D25, D29 and D936 roads, some 10 south of Abbeville and 25 miles (40 km) west of Amiens.
The name has its origins in Celtic religion and mythology, as ‘mont of Ésus. Over the centuries, it has been known as Ossemons,Aussemons and Wessemont. There is evidence pointing to Acheulean origins and Roman occupation.
By 1275, the town was the seat of the provost of the Vimeu.
The Templars of Acheux became a part of the bailiwick of Oisemont, setting up a preceptory of the house of Aisseu.
In 1307, a second headquarters was set up by the Knights Hospitaller. The building still stands today, in the ‘rue de la Commanderie’, as do several other historic buildings
The castle was destroyed in 1346 by the army of Edward III during the Hundred Years War. It had defensive ramparts to protect the inhabitants in times of attack. It was rebuilt and destroyed again in 1370 by John of Gaunt.
A Templar hospital was built on the site of the present old-peoples’ home. All that remains is a stone cross.
The year 1472 saw Charles the Bold set fire to the town, reducing it to ashes.
During the Wars of Religion of the 16th century, the town was an important Protestant centre. By the 17th century, the Huguenots were hiding in underground passages for protection.
