Light border fortification
On your way to Luční bouda past Kaplička you can notice concrete buildings of the second sequence barring the saddle between the mountains Luční and Studniční. The first sequence was to bar the plateau near Luční bouda and to contain two buildings of heavy fortification. Many rests of the war fortification were preserved in the whole area. The building number 256 is the highest located fortification object in the Czech Republic.
