The webcams will be on tomorrow and for a while yet. I am not sure when the best time is if you want to see the sun on the wall of the inner chamber, ia it sunrise, sunset or what. Must see if I can find out. I've looked on previous years and it is pretty impressive if there are no clouds.
I have been there, but not at the solstice. A very interesting place. It is a bigger mound than you would think, 100ft across and 36 fy high .
You have to bend right over to get in. The Viking graffiti on the walls includes a comment by Erlingr who followed Ingebjork in - "Ingebjork the fair widow - many a woman has walked stooping in here a very showy person" Personally I was quite glad that it was Mr E who followed me up the long narrow tunnel and not a randy Viking, but perhaps Ingebjork did not complain.
