Stacked stone walls and boundaries are a vital aspect of Pag’s past and eternal monuments to the arduous life of Pag’s labourers, who built and maintained them for centuries. Based on the length of the preserved stacked stone walls of approximately one thousand kilometres, the island of Pag is one of the richest areas in Croatia for this type of construction. They were erected as natural boundaries between pastures, high enough so that sheep could not jump over them and sturdy enough so that they could not be toppled by strong winds. Their construction was not easy. Activities aimed at the protection of stacked stone structures on Pag were initiated due to the exceptional importance of stacked stone walls, and to prevent their destruction.
