Hay barrack

[1] Hay barracks were widespread in northern Europe in medieval times, also found in the Alps and North America, but are rare today.

[2] Hay barracks were used in much of Europe and parts of colonial America, but were very common in the Netherlands, where they are called hooiberg or kapberg.

The roof is typically thatched and lightly framed to limit the weight.

The posts often have holes to place pins at various levels as the height of hay pile changes.

More modern versions may have cables on winches on each post so the roof is easier to move.
