From Arutz-7:

Hundreds of women came out last night to celebrate the Tu B’Av (15th of Av) holiday on the biblical site of Shiloh in the Benjamin region, renewing an ancient tradition. For centuries, the young women of Shiloh would go out to the vineyards and orchards and dance on the joyous holiday of Tu B’Av. Last night, the women returned to the orchards in a multifaceted celebration of dance, organized by the Benjamin Regional Council.

The story of the women dancing is recorded in Judges 21.  There the women didn’t fare so well when they were carried off by surviving scoundrels from the tribe of Benjamin.
