What is now Calderwood stands adjacent to what was once a narrow stretch of the river that for centuries was used as a
ford by
Native Americans. By the 18th century, the
Overhill Cherokee village of
Tallassee straddled both sides of this ford. This village was burned by Colonel
John Sevier in 1788 in retaliation for the Nine Mile Creek massacre, which took place a few miles to the north. When Alcoa began developing the Little Tennessee Valley around 1909, the Calderwood area was part of a farm owned by Blount County farmer John Howard. After purchasing the property, company engineers began using it as a base of operations. In 1912, a post office was set up in the base camp, which initially used the company's name, "Alcoa." Under engineer I. G. Calderwood's leadership, a railroad line was constructed to connect the base camp with the Southern Railway terminal at Chilhowee (near modern
Chilhowee Dam). Alcoa's Little Tennessee Valley plans were finalized in 1915, and construction crews began arriving at the company's base camp. Cheoah Dam was completed in 1919, and Santeetlah was completed in 1928. In 1919, the large company town that housed the workers for Alcoa's aluminum plants, which had previously been known as "North Maryville," was incorporated under the company's name. The following year, the company renamed its Little Tennessee Valley construction camp "Calderwood" after its able head of operations in the valley, I. G. Calderwood. After the completion of Calderwood Dam in 1930, the construction camp evolved into a community that housed maintenance crews for the dam. Nearly two dozen residences were built, all following identical one-floor plans. After
World War II, Calderwood expanded. In 1950, a school was built, and a Quonset hut was installed in the community for use as a theater. The Calderwood Methodist Church was completed in 1954, and the Calderwood Baptist Church was completed the following year. Within a few years, the need for onsite crews diminished, however, and residents began moving away. By the late 1960s, Calderwood had been largely abandoned. ==Historical structures==
