La Sergenté passage grave on . dates from approx 4500 BC and is the only corbelled passage grave known from the Channel Islands, and possibly the earliest dolmen on the island. The main chamber is about 12 feet across, it was excavated in 1923. Photo by our member Karolus, more on our page: https://www.megalithic.co.uk/article.php?sid=14829

Any azimuth for the passage opening?

Avid amateur archaeo-astronomer here!

Very interesting that it’s the only one!

@NoctisEqui follow the link I gave for our page then look for the coloured square buttons in the middle. Try these for various maps and aerial views which will show the azimuth.
