Esthetically already, Sainte-Colombe church, built between 1858 and 1870, is an edifice subtly blending the neo-Romanesque with a few Gothic elements: pointed steeple, ribbed crossing, etc…
The real treasure is a magnificent 16th-century carved furniture from the Dames de Sainte-Colombe abbey, as well as a stela in tribute to its Great War aviator hero, Jehan de Terline, born in 1892 in Blendecques.
The young fighter, born on July 21, 1892 in Blendecques, entered the Neuvième régiment de cuirassiers in 1914.
Becoming a skilled aviator, he scored two victories in 1916, but it was the third that made him a household name. On July 27, 1916, running low on ammunition, he deliberately chose to swoop down on his adversary, a German albatross, which was carrying out important photo missions. After the collision and a vertiginous fall, both the German crew and the valiant aviator died in the crash. This deliberate boarding would be seen as an act of great bravery, and would earn the Blendecquois posthumous fame.
