The Mount Horeb Mustard Museum in Mount Horeb, Wisconsin, features the world’s largest display of prepared mustards. It is often featured in lists of unusual museums in the United States.

Among the diplays are sweet hot mustards, fruit mustards, hot pepper mustards, horseradish mustards, and even spirit mustards. The collection includes a large variety of French and English mixes, but many other countries are also represented.

The museum opened its doors on April 6, 1992, and moved across the street to its present location in October 2000. It will be moving to Middleton, Wisconsin, in late October 2009. Admission is free of charge, and the museum is open between 10 a.m. and 5 p.m., though it is closed on Easter, Thanksgiving, Christmas, and New Year’s Day.

On the first Saturday in August, the museum sponsors an annual celebration of National Mustard Day.
