What we see today is only part of the original monument. There were originally more standing stones, perhaps as many as 30, some measuring up to 6 feet in length. The site was damaged prior to WWII when the military removed some stones from the east side of the circle and used the circle for target practice.
At the centre of the cairn is a depression that suggests a cist, or grave. The hole was left by treasure-hunters in the 19th century. If there were any remains at the centre of the cairn they were removed, so we are left to speculate on what the circle and cairn might have looked like and what its purpose was.
Why the combined stone circle and cairn? Perhaps Bryn Cader Faner was a result of different traditions, brought together at one site. It probably dates to the 3rd millennium BC. The circle stands on the brow of a rise, so that as you approach from the south it is outlined against the horizon, increasing its visual impact. This must have been intentional, and the site was created to make a statement.
A good OS map and waterproof hiking boots are essential! There is a small parking on a no through road past the Maes-Y-Neuadd hotel (LL47 6YA) near Talsarnau.
