Historic Field Lime Kiln

The targeted processing of limestone into a versatile building material is one of the oldest and, to this day, most important technical production processes. The oldest evidence of lime production for use in screed-like floors of cult sites comes from the mountain temple of Göbekli Tepe in Anatolia and is 11,000 years old. The art of lime burning was already widespread in ancient times. Originally, wood, peat, or coal were used as fuel. The first facilities for this purpose were so-called charcoal kilns, while later simple field kilns without walls were used. Simple earth pits, in which lime was still burned in the 20th century, can be found in large numbers in the densely forested Bükk Mountains in northeastern Hungary.Source: Wikipedia
