The best place to begin a visit to the Somme battlefields – especially if you're interested in WWI's historical and cultural context – is the outstanding Historial de la Grande Guerre in the town of Péronne, about 60km east of Amiens. Tucked inside Péronne's massively fortified château, this award-winning museum tells the story of the war chronologically, with equal space given to the German, French and British perspectives on what happened, how and why.
The museum contains a unique collection of visually engaging material, including period films and the bone-chilling engravings by Otto Dix, which capture the aesthetic sensibilities, enthusiasm, naive patriotism and unimaginable violence of the time. The proud uniforms of various units and armies are shown laid out on the ground, as if on freshly – though bloodlessly – dead soldiers. The lake behind the museum is a fine place for a stroll or picnic.
