Most of the visitors to this celebration of a lost, or discarded, way of life, have been happily steeped in the minutiae of Downton Abbey, where life “in service” was shown to be at least as interesting as the life of those served. Although we visitors get to walk beyond the green baize door separating the family’s living areas from the servants’, the upstairs rooms aren’t quite as well represented because they were real, shot on location at Highclere Castle, which played the role of Downton Abbey.

Placed throughout the three-level exhibition are larger-than-life photos of familiar characters; also there are videos of Mr. Carson, the butler, and Mrs. Hughes, the housekeeper, whose sudden “appearances” allow them to welcome us to the house and bid us farewell.

Commercial exhibitions such as this one are more like World’s Fair installations than exhibits in proper museums. But I’ve been to the French fry museum (in Bruges, Belgium), a chocolate museum (Barcelona), the pasta museum (Rome) and others, and I find that the wall plaques and artifacts in these displays are more detailed and give more historical and social context than those in many a Smithsonian exhibit.

They are also often more fun: There’s a fun interactive quiz, an “application for employment,” that told the woman ahead of me that she qualified to be a Lady’s Maid, an “upper servant” who traveled with her mistress, did her hair, helped with dresses and accessories. Another visitor got the sober news that she would have to start as a House Maid. Me? I was promised my own domain, as Cook, with my own posse of Kitchen Maids and outside purveyors, housekeeping logs—and the longest work day of any of the downstairs lot. Lucky me!
