In the early 20th century, the North End was dominated by Jewish and Italian immigrants. Three Italian immigrants founded the Prince Macaroni Company, one example of the successful businesses created in this community. Also during this time, the city of Boston upgraded many public facilities in the neighborhood: the Christopher Columbus School (now a condominium building), a public bathhouse, and a branch of the Boston Public Library were built. These investments, as well as the creation of the Paul Revere Mall (also known as the Prado), contributed to the North End's modernization.
