Žabljak Crnojevića is an abandoned medieval fortified town in Montenegro located on the confluence of the Morača river in Lake Skadar. It is believed that this fortress was founded in the 10th century during the reign of the Vojislavljević dynasty in then-known Dioclea, whereas the first known written testimony of the fortress originate from mid-15th century.
The fortress served as the capital of Zeta under the Crnojević dynasty from 1466 till 1478, being the seat of Stefan and Ivan Crnojević. However, Ivan Crnojević was forced to move the capital in 1478 when the Turks seized the town during the siege of Shkodra, holding it until the decision of the Berlin Congress in 1878 when it fell under Montenegrin administration once again after 400 years of Turkish rule.
The town has tall walls with towers, as well as one gate. Within the walls can be found Ivan Crnojević's court, Church of Saint George (was turned into a mosque during Ottoman rule), housing and military facilities, a warehouse for clothes and a water tank, most of which are preserved.
In the early 17th century, the town was under Turkish rule. The fortress had only one resident, the Dizdar Aga (Turkish official).
References: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.
