2 Best Sights in Limburg Province, Antwerp and the Northeast

The Gallo-Roman museum traces the region's human history, and features a host of local archaeological finds, not just from Roman days but all the way back, via the Celts, to the original Neanderthal settlers. To get the kids inspired, ask for the special child-oriented audio guide, which features stories told by the archaeologist "Bob the Digger."

A 10-minute train ride, or drive, northeast from Hasselt, this huge open-air museum features around 150 mostly agricultural buildings, in different architectural styles, that were brought here stone by stone from all over Flanders, and rebuilt in a series of regional clusters across a largely wooded site. Many of the buildings date back to the 17th century, and they are furnished and decorated with thousands of pieces of period furniture, farm equipment, and general bric-a-brac. There are themed events here throughout the year, including Sunday walks even during the winter shutdown when the museum buildings are closed. Bring walking shoes: the whole site covers a whopping 2 square miles.
