Bryn Cader Faner

Bryn Cader Faner is a Bronze Age round cairn which lies to the east of the small hamlet of Talsarnau in the Ardudwy area of Gwynedd in Wales.

[1] The diameter is 8.7 metres (29 ft) and there are 18 thin jagged pillars which jut upwards from the low cairn.

[2] It is thought to date back to the late third millennium BC.

The site was disturbed by 19th-century treasure hunters, who left a hole in the centre, indicating the position of a cist or a grave.

However, before the Second World War, the British Army used the site for gunnery practice.
