As you cross the causeway over to Berneray there is a hill right in front of you, a small modern cairn crowns its summit. Park, jump fence, go up, pass little cairn and the standing stone is quite visible, at 8ft6 you wont miss it.
A mucho complicato place this(that's Italian, don't ask me why), the stone is tall and fine and by shape almost stolen from Stenness, hoary moss and yellow lichen occupy the upper half of it, fantastic views of distant hills and white sandy beaches.
Now the complicato, right next to the menhir is a rectangular structure, canmore says it's a very old chapel, they also have an aerial picture showing the stone and chapel sitting in a large oval/squarish enclosure, apparently an old burial ground, they then go on to call the whole structure a Cashel, like what they have in Ireland.
Then they say that part of the enclosure wall could once have been a cairn.
So there was much going on here over a long period of time, which is nice.
Just over the hill is a possible chambered cairn, it's not on my map but i'm still kicking myself for not having the time or the wits to find it.
This is very a nice place, we lay down among the wild flowers and watched birds and flying insects whooshing about, rested our heads on the chapel wall, of course we didnt know it at the time.
