berangere444, So, the Journées du Patrimoine are this week-end ( https://journeesdupatrimoine.culture.gouv.fr/ ) and it's been a few years now that they are the "Journées Européennes du Patrimoine" so the hastag is #JEP2023 . I checked and in English they are the European Heritage Days but the hashtag EHD2023 does not exist.
What's the hashtag ?
Or is it that despite the "European" in the name in fact only the French take part ? (I don't mind tooting in French) @archaeodons #archaeology
