Created in 1919, the Méry-la-Bataille national necropolis contains the remains of 1,538 soldiers who died for France during the Battle of Matz in June 1918. Adjacent to the municipal cemetery, it brings together the bodies exhumed from various temporary cemeteries in the Oise, of which 1,286 are buried in individual graves and 254 in two ossuaries. This memorial pays tribute to the soldiers who fell during one of the decisive offensives of the First World War, which helped halt the German advance towards Paris.

The Église Saint-Jean-Baptiste in Plessis-de-Roye is an exceptional example of reconstruction architecture with a deeply symbolic meaning. Originally built in the first half of the 15th century, the church was almost completely destroyed during the First World War. It was rebuilt between 1930 and 1932 by the architect André Collin, who deliberately chose to leave the nave unfinished. This gave the church the character of a small cloister — a powerful symbol of loss and remembrance of the devastation of war.

The village played an important role during the First World War. It was occupied on 30 August 1914 and was the scene of fierce fighting during the “Race to the Sea” and again during the Battle of Matz in June 1918. The village was badly damaged and was awarded the Croix de Guerre for its suffering and courage.

After the devastation of the First World War, a new church dedicated to Our Lady of the Assumption was built in Fresnières in 1929-1930. Its architecture reflects the spirit of the time: a combination of neo-Romanesque forms and Art Deco elements. The round arched windows and the barrel vault in the nave refer to the classical Romanesque style, while the mosaic portal and the straight lines of the bell tower clearly reveal the influence of Art Deco. Above the portal, a fresco with a historical inscription dating back to the time of Louis XIV is a subtle reminder of the long history of this place.

The Château de Boulogne is unlike any other. With an architecture drawing its inspiration from history and esotericism, it was born in the imagination of Charles de Boulogne (1864 - 1940), a rich Belgian landowner who purchased the title of Count and who undertook the construction of the castle in 1896 on the remains of the Lancry family castle. For 25 years, he put all his energy and his fortune into creating his 'Great Work', a philosopher's residence, a castle of Mysteries which unfortunately was largely destroyed during the Battle of Matz in 1918. For his fellow citizens, Count Charles de Boulogne was the builder of a spooky residence. An incomprehensible man, a little crazy, an “enlightened person”? And yet the sentence he had engraved on the portal gives us the key: “Sortis patiens esto nulli clauderis honesto” ("Be patient, nothing is closed to an honest man")
