Diest, Belgium

With a population of just 23,824, Diest is a sleepy Flemish town that offers little in the way of modern amenities. The city is surrounded by high ramparts, a legacy of its military history that now feels more like a burden than a charming relic. Bureaucracy is a persistent headache, as evidenced by the city's repeated failed attempts to redevelop its vacant citadel. While the Grote Markt and historic churches provide some visual appeal, the lack of economic opportunity and cultural vibrancy make Diest a tough sell for all but the most dedicated Belgophiles.
