There are many of these old kilns in the Highlands where farmers use to roast limestone to produce lime fertiliser. The discovery that the application of lime neutralised the acid in the soil transformed agriculture in the Highlands in the last century, increasing yields three-fold in some areas.
This kiln was constructed around 1865 to meet the growing demands for lime to improve the land for pasture and crops. Beforehand the lime quarried here had to be taken to Strathtay to be rendered in small open kilns. The kiln went out of use in the early 1900s.
