Castrati were male singers with artificially created soprano or alto voices that were the result of castration in boyhood. Possessing powerful voices of great range and unique sound, castrati were introduced in the 16th century. They were especially popular in churches and operas in Europe during the 17th and 18th centuries and even sang in the Sistine Chapel choir until 1903.
