As a further improvement there was also added a line of shelters to protect personnel from aerial bombing and artillery bombardment.
The distances between each was 300–400 meters and most of them were located in direct proximity to the sea, built according to a number of standardised designs.
During the Cold War the line was strengthened further, adding turrets armed with 75mm tank guns, either as additions to already existing fortifications or in newly constructed ones.
The "liquidation" referred to here is not the physical removal of the reinforced concrete found everywhere along the coast of Scania, but the emptying of the bunkers and shelters of all military equipment.
The refurbished bunkers were officially inaugurated on May 30, 2009 with battle demonstrations, the firing of salutes, fanfares and color guard processions.
