Utvrdu Strač izgradila je austro-ugarska vojska od 1910. do 1916. godine s ciljem zaštite jugoistočne granice Bosne i Hercegovine. Bila je to druga po veličini austro-ugarska vojna utvrda u monarhiji. U njoj su bile smještene austro-ugarske trupe do 1918. godine. Utvrda je bila naoružana sa dva topa od 100 mm, dva manja topa, 24 mitraljeza i 12 reflektora. Na vrhu utvrde su četiri željezne kupole - do pola ozidane a od pola uklesane u stijeni.

The hoods were pulled out with a "Austrian Daimler" artillery tractor.

Soldiers had diesel machine for electricity. Today, most of the Strač is ruined, but one part is still preserved.

This place has enormous tourist potential.

Construction of Strač was never completed, as Montenegro capitulated in 1916. When the construction of Strač began in 1910, the construction of four domes was planned, but only two were built. Strač was designed on the basis of similar fortifications in Italy and he was supposed to provide protection from 240mm cannons. The fort was built with modern concrete construction. Fallen Austro-Hungarian soldiers were buried outside the fortress, which can still be seen today.
There are official data that there were five officers and 157 soldiers on Strac in the last Austrian military crew, while the commander was Ferdinand Zahradnik, in charge of the captain. Strač was used for military purposes well after WWII. Once the military had withdrawn, all the furnishings and most of the steel parts were removed. The howitzer battery and the barracks suffered the most devastation. Despite this damage continues Strač is an attractive destination and the last Austro-Hungarian fortification where the M9 howitzer cupolas are still preserved in situ.
