An introduction to pre-industrial lime kilns. A lime kiln was a structure used to manufacture lime (calcium oxide) by burning calcium carbonate at temperatures above 900°C. The calcium carbonate burned (or 'calcined') was commonly limestone or chalk, but occasionally other materials such as oyster or egg shells were used.

Apparently, some people use this as a hangout and drinking spot and then leave ...
The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime. Hydrated Lime
