In Spillville, Iowa, the Bily Clocks Museum preserves handmade clocks created by Frank and Joseph Bily between 1913 and 1958. Born in Spillville in the late 19th century, the brothers worked as farmers and carpenters, and their hobby of clockmaking developed into intricate folk art that combined timekeeping, detailed wood carving, and imaginative mechanical scenes. Notable pieces include the American Pioneer Clock, a version of the World's Smallest Church, and the Apostles Parade Clock. The building also connects the collection to wider cultural history through Antonín Dvořák, who spent the summer of 1893 there and completed his Symphony No. 9 in E minor, From the New World.
