Of all the many WWII museums commemorating the Battle of the Ardennes, Diekirch’s Musée National d’Histoire Militaire is the most comprehensive and visual. What was once a brewery building 200m north of the town centre, is now packed full of WWII equipment, vehicles and memorabilia. Numerous well-executed mannequin scenes illustrate the suffering and hardships of the battles fought in the thick snows of Christmas 1944.
If you've got a Luxembourg Card you might spend a few minutes peeping into Diekirch's other cursory attractions. Just off the café-ringed central square, Place de la Libération, the slate-spired Église St Laurent is built on the foundations of a 1500-year-old Roman hall whose heating system can be vaguely discerned in the crypt. Close by, MHsD is the brand new city museum, but despite valiant attempts to captivate, the only really memorable exhibit is the Roman mosaic floor from a villa site nearby.
Two minutes' walk southwest on the town’s modest inner ‘ring road’, the one-room Brewery Museum celebrates Diekirch Beer, the Grand Duchy’s best-known lager. The rather elevated ticket price also allows you to peruse a modest car collection in the same building. Neither could be described as gripping.
One block north of Place de la Libération, Hotel Au Beau Séjour has rooms that aren't nearly as gloomy as the corridors might suggest. It’s 700m from the co-habiting train and bus stations to Place de la Libération. Direct trains arrive hourly from Luxembourg City (30 minutes) or you could do a train-bus combination (37 to 47 minutes) via Ettelbrück (10 minutes). Bicycles can be hired from Rent-a-Bike on the parallel street behind (west of) the car museum.
