Nine Maidens Downs is a moorland southwest of Four Lanes in Cornwall, England, UK.
Half of this circle survives with a semicircle of five stones, four of which are free standing and the other is built into the Cornish hedge in its original position.
[3] Half a mile west of the stone circles, on a prominent ridge, is the massive Bronze Age cairn of Hangman's Barrow.
The centre has suffered from past tomb robbing attempts and nothing is known of its original contents.
[3] Nine Maidens is the source of the river Cober which rises between Hangman's Barrow to the west and the Nine Maidens stone circles to the east and runs to the west of the town of Helston before entering the largest natural lake in Cornwall – Loe Pool.
