It's the gift that keeps on giving. St Lythan's (Gwal y Filiast - Lair of the Greyhound).
The name may be an Arthurian reference or one of the many forms of a female deity back in 4000BCE. Both suggestion have been made by local enthusiasts.
For the record, there are many Arthur toponyms in the Vale of Glamorgan area, I had a list using OS maps from past 50 years. (Will post if I can find it!).
Anyway, 2 reasons for this post. One to share the excitement the prize-winning photo featured earlier of the arrowhead light through the south-facing stone of the dolmen.
Secondly, for anyone who can get to the dolmen over the vernal equinox, you will see and can film the moment the sun at sunset kisses the horizon and shoots through the porthole for around 5-10 seconds. It's easier now as at the autumn equinox the horizon trees are in leaf and get in the way. The vernal equinox is perfect. Just need clear sun at sunset and the cows probably won't be out grazing till later in the year.
We did ours in 2017. ( See www.thecelticway.org) With more people filming it, maybe CADW will update their information board to mention this function of what I believe is a manmade porthole, not natural one. CADW have only recently conceded the E/W alignment of the site.
A future topic perhaps worth a search is the way the hilltop above the site potentially relates to the Somerset hills across the Bristol Channel.
Something is not right. This message is just to keep things from messing up down the road
