High Quality Content by WIKIPEDIA articles! A chimney sweep is a person who cleans chimneys for a living. The occupation of chimney sweep is considered to be one of the oldest in the world, as chimneys have been around since ancient times, though it is only in the last two hundred years that the chimney has grown large enough to hold a man, giving rise to the image of the chimney sweep as it developed in the time of the Industrial Revolution. In the fifteenth and sixteenth centuries in Western Europe, construction of rooflines with crow-stepped gables became common to allow chimney sweeps convenient access to the chimney top. With the increased urban population, the number of houses with chimneys grew apace and the occupation of chimney sweep became much respected and sought-after, although it is sometimes derided in verse, ballad and pantomime.
