Lime Oven Hampfrosa
This arched entrance acted as fire mouth. With a burn time of one week, 15 tons of lime could be obtained. When it was no longer needed, they filled and covered it in about 1950 with soil. The Archaeological Service has it exposed again in 1988. The oven is now under monumental protection. Felsberg, Graubünden, Switzerland, Aug 17, 2012.
