During the construction of the checkpoint in the area of Plitvice Lakes, during the deployment of our soldiers to the UNPROFOR mission, during the felling of one of the trees intended for the construction of the checkpoint, a shrapnel was discovered, which was embedded in the trunk of the tree and most probably came from World War II. Subsequently, the shrapnel with a piece of the surrounding log was removed by one of the soldiers and kept as a souvenir.
