In page Babi Yar:

"

The Babi Yar (Babyn Yar) ravine was first mentioned in historical accounts in 1401, in connection to the sale of it by baba (an old woman) who was also the cantiniere in the Dominican Monastery.[1] The word yar is Turkic in origin and means "gully" or "ravine". Over several centuries, the site was used for various purposes, including military camps and at least two cemeteries, including an Orthodox Christian cemetery and a Jewish cemetery. The latter was officially closed in 1937.[citation needed]
