Landro works

The Landro roadblock is an Austro-Hungarian fortification built in Eastern Tyrol (now part of Northern Italy). Due to the hilly construction site, the roadblock had to be built in two parts, the mortar battery and the higher cannon battery. Landro was the largest fortification in Subrayon V of the Austro-Hungarian fortifications on the Italian border. The roadblock was crewed by 6 officers and 184 enlisted men. During World War I, the roadblock was the seat of command for Subrayon V. The mortar battery was constructed between 1884 and 1891, and the cannon battery was built between 1887 and 1894. Both were connected by an underground postern. Landro was one of the first fortifications built by Austria-Hungary that used concrete and steel in the construction.
