Noblesville Milling Company Mill, also known as the Model Mill, is an historic grinding mill. The original section was built about 1872, and subsequently expanded to cover 1/2 a city block. It is a large brick structure, with the largest section being four stories tall. It includes a water tower built about 1903. It was originally built as a planing mill, but later converted to a grinding mill to produce flour.
It was listed on the National Register of Historic Places in 2001.
