In Bruges, nestled among the Gothic architecture and outdoor cafes dolling out beer and waffles, lies the world’s only museum dedicated to fries.

While some might call fried potatoes “French” fries, it’s well known that Belgium is the real source of pommes frites, and the Frietmuseum pays tribute to this national cuisine. Inside a 14th-century building known as the Saaihalle, founders Cédric and Eddy Van Belle have assembled a curious collection of artifacts, equipment, and art. Their museum traces the history of the fry, from Andean potatoes to Belgium’s iconic paper cones of crispy, hot pommes frites. There’s an Inca-era vase featuring potatoes, dioramas of Peruvian farmers and potato-peeling European soldiers, vintage ads, an extensive assortment of potato cutters, and a mobile of dangling tubers of various hues and sizes from around the world.

After working up an appetite, visitors can descend to the medieval cellar, where a cafe dishes up pommes frites, among other items such as croquettes and beef stew.
