The Bily Clocks Museum is located in Spillville, Iowa, United States.[3] Frank and Joseph Bily were born in the late 19th century in Spillville, Iowa.They took up clockmaking as their hobby, carving and creating complex, finely detailed works of art out of wood.[4] The Bily brothers were originally going to burn their creations when they died, but they later donated their collection to the city of Spillville.[5] The Czech composer Antonín Dvořák spent the summer of 1893 in the building, which is where he completed his Symphony No.
