The term bog bodies (or bog people) is used to refer to human burials, some likely sacrificed, placed within peat bogs of Denmark, Germany, Holland, Britain, and Ireland and naturally mummified. The highly acidic peat acts as a remarkable preservative, leaving the clothing and skin intact, and creating poignant and memorable images of people of the past.
The reason that bogs permit a high level of preservation is because they are both acidic and anaerobic (oxygen-poor). When a body is thrown into a bog, the cold water will hinder putrefaction and insect activity. Sphagnum mosses and the presence of tannin add to the preservation by having anti-bacterial properties.
The total number of bodies pulled from European bogs is unknown, partly because they were were first rediscovered in the 17th century and records are shaky. Estimates range wildly between about 200 to 700. The oldest bog body is Koelbjerg Woman, recovered from a peat bog in Denmark. the most recent dates to about 1000 AD. Most of the bodies were placed in the bogs during the European Iron Age and Roman period, between about 800 BC and AD 200.
