South Indian haystacks look very similar to these. In fact, in my childhood, I used to classify them as circular and squarish - these referred to the bases - with appropriately shaped tops.
Indeed, as someone who grew up in a South Indian city (Mangalore), my parents would send me off to stay with my agrarian relatives in the countryside during summer holidays, and haystacks like this were all over the place. Fast forward a few decades and I've seen conspicuously similar haystacks in Romania.
Weirdly enough I’m a Mangalorean now in Romania :)
Nice, how are the haystacks going ? :-D
Ha I’m a Mangalorean too and made a similar comment a little before yours.
