Earth oven

An earth oven, ground oven or cooking pit is one of the simplest and most ancient cooking structures. The earliest known earth oven was discovered in Central Europe and dated to 29,000 BC.[1] At its most basic, an earth oven is a pit in the ground used to trap heat and bake, smoke, or steam food. Earth ovens have been used in many places and cultures in the past, and the presence of such cooking pits is a key sign of human settlement often sought by archaeologists.
