The stronghold VIIIa on Kučino brdo was built in the same period as the stronghold VIIa. The large facility was used for surveillance of the territory, rest and regrouping of the army. The remains of an ammunition depot can be found above it.

By 1900, three revolutions had taken place in Europe's military industry: in transport, in small arms fire, and in artillery. The soldier came out of the railway car well-rested, the machine gun developed into the deadliest weapon, and what decided the outcome of the battles was the artillery - steel barrel pipes, with a range of 8 km and smokeless gunpowder. This technological revolution concentrated the defense of the border into strong fortresses. In the early 1980s, these were stone towers, reinforced with artillery platforms. Before World War I, the only safe protection was in armored fortresses. But you will find out more about that when you get to Strač.
