Every year the town remembers its Dutch heritage with a two-day celebration, the Holland Fest, held in Memorial Park the last Friday and Saturday in July. The festival features ethnic foods, music, and 2-mile and 10K runs. Before the Saturday afternoon parade the main street is scrubbed by children and adults dressed in traditional Dutch costumes to prepare the road for the Klompen Dancers and parade to follow. Another nod to the village's Dutch roots is a full-sized replica windmill in Windmill Park downtown. In addition to Klompen Dancing, the festival also holds an annual wooden shoe race where children race one another while wearing traditional Dutch wooden shoes. The festival also is known for its Oliebollen, which is a type of Dutch doughnut. Holland Fest is one of the largest "dry festivals" in Wisconsin.
