Looking for Seven Valleys homes for sale? Look no further. Seven Valleys is a small borough in southern York County. The Seven Valleys basin was settled by forty families of the German Lutheran and Reformed faiths. They came from the Hunsruck Mountains of the Rhineland Palatinate and arrived in the Codorus valley during the early fall of 1738. The lush meadows and gently rolling hills here reminded them of their homeland, even to the presence of seven valleys in the area, and they called it Das Siebenthal, which in German means Seven Valleys. Seven Valleys incorporated in 1892. Over the years, the discovery of iron ore, and cigar and ice cream plants provided jobs for the area. Today, Seven Valleys is a quiet residential and agricultural area. Seven Valleys is served by the Dallastown Area School District.
