The claim that it is unique to Romania seems to be mistaken, and sensationalized. I wished writers wouldn't do such.

Are the stacks more then 4m tall and you build them with someone on top , while someone else lifts the hey with a long fork? I am curious if are similar or smaller in dimensions.

If anything I’ve seen them much higher than 4m. Yes, a person stands on top to lay out the layers. Not sure if a long fork is used.

yeah, it can be higher, You have no choice then to use a long tool to raise the hey as high.

The funny coincidence is that I am from Romania and I just helped my grandfather with raising the hay on the haystack yesterday evening but we started a new stack so we are not at the top yet.
