One of the finest First World War museums in the world, In Flanders Fields occupies the upper floors of the rebuilt Ypres Cloth Hall — itself a powerful statement, since the original Lakenhalle was entirely destroyed in the war and reconstructed over twenty years from the ruins. The museum covers the entire Ypres Salient and the experience of the war, from the political origins through the grinding attrition of the trenches to the aftermath and memory.
What sets it apart from most war museums is the deliberate focus on individual human stories. At the entrance you register a bracelet encoded with the details of a real person who was present at the Salient — a soldier, a nurse, a civilian — and their fate is revealed gradually as you move through the exhibition. The technology is clever, but the effect is emotional rather than gimmicky. The exhibition design is outstanding, using original objects, photographs, and sound to build a picture of what the war actually felt like from inside.
Allow at least two hours. The museum is open daily except some Mondays in winter; check the Ypres tourism website for current hours.
