When we moved to the island we currently live on, our address was in a road called 'Solsteinen' (The Sun Stone), but I didn't think anything of it until I realized that the roughly hewn stone serving as the property limit marker was juuu-uuust touched by the sun on Winter Solstice. Aha.
A quick call to the local archaeologist confirmed my suspicion - 'Oh, so you're the new resident there, I'd planned on being in touch - that stone monument has been there for more than 2000 years, is A-listed and please, whatever you do, don't do anything with it. Seriously.'
