The military Fort Venini in Oga was erected in the defense of the main alpine passes of the Alta Valtellina, and was built between 1908 and 1914 in the village of Dossaccio. The fort’s structure is decidedly massive and includes four armoured domes in steel where there were the cannons, that thanks to the particular orientation east-west, could rotate and defend all the valleys and the passes potentially subject to danger from the enemy.

Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
