This is exactly what it says: a museum dedicated entirely to salt and pepper shakers, with over 20,000 sets on display from around the world. The collection was started by a couple from Bolivia and donated to Gatlinburg, where it found a natural home among the town's other singular attractions. The shakers range from the mundane (standard diner sets) to the genuinely bizarre — figural pairs, novelty themes, hand-painted ceramics, mid-century plastics, and objects from dozens of countries that you would never have guessed had a salt and pepper shaker tradition.
It's a small museum and takes maybe forty-five minutes to get through, but the cumulative effect of 20,000 pairs arranged in cases is oddly hypnotic. Gatlinburg has no shortage of kitschy attractions, but this one has a sincerity to it — someone spent decades collecting these things because they genuinely found them interesting, and that enthusiasm carries through the displays. Worth the small admission fee, and reliably entertaining for people who find the premise absurd and people who find it charming in equal measure.
