Beginning in the 1840s, several frame mills operated on this site, harnessing the power of Shaw's Creek to produce yarn and blankets. Benjamin Ward built a substantial four-storey stone mill in 1881. Although the massive beams for the building were Georgia pine, much of what we see today in the Millcroft Inn is a local product: the beautiful stone came from the quarries at nearby Inglewood and the mortar was processed at the Alton lime kilns. Just across a laneway from the mill was a handsome stone warehouse, connected to the mill by way of a steel catwalk manufactured by Dicks foundry in Alton.

Ward's son-in-law, John M. Dods, purchased the mill, commonly know as the "Upper Mill," in 1892. The original power for the Upper Mill was a single water-driven turbine in the basement. The turbine was connected to the mill machinery by a series of pulleys and belts. As the water table lowered, the Dods were forced to install a steam generator with a boiler powered by soft coal.

Running a knitting mill was not without its challenges. In November, 1889, dam breaks along Shaw's Creek created considerable damage in the mills and throughout town. And, in 1917, a disastrous fire destroyed Dods Mill. In the subsequent reconstructed building, the third floor became a water tower and sprinkler system that prevented similar loss to fire in the following decades.

The Ward and Dods mill (later Dods Knitting Mill) became a nationally-known competitor of the Stanfield company, producing woollen long underwear, a valuable commodity in the days before central heating. During World War I, thousands of Canadian and British troops were kept warm with Dods products. Owner John Dods was a leading citizen of Alton, known for this generous treatment of employees and involvement in charitable works. Both the mill and the man were integral to Alton's development. John Dods died in 1923 and the firm continued to run under James and Andrew Dods, and later, under lease to the Toronto Millstock Company of Waterford. In 1965, the mill ceased production and the contents of the building were sold.

History was not finished with the property on the millpond in Alton, however, for the natural beauty of the site and the rugged stone mill became a focus for tourism development in the region. The original stone mill is now the the Millcroft Inn, which uses an advantageous location close to Toronto to serve both the corporate meetings market as well as leisure guests attracted by beautiful rooms and excellent cuisine. John Dods would recognize much of the historic inn: guest rooms and dining rooms overlook the millpond and the sparkling waterfalls cover the mill dam. The Dods warehouse is now a comfortable meeting facility, and Dods' own spacious home is now the Manor House, with heritage-inspired accommodations.

The Millcroft Inn and Spa builds on the Dods' tradition of community development through involvement in local arts and tourism initiatives and leadership in the development of outstanding regional cuisine. And more recently, the Millcroft Inn has created a European-style "Health and Wellness Centre" that will maintain the mill's position at the forefront of the local economy.
