The Earl"s Palace is a ruined 16th-century castle. It was built by Robert Stewart, 1st Earl of Orkney (1533–1593), illegitimate son of King James V and his mistress Euphemia Elphinstone.
The castle was constructed in two phases. The first phase of work, begun in the 1570s, consisted of the great hall located in the south range, above the main door. Beside this was Lord Orkney"s private chamber in the south-east corner tower. An inscription above the entrance, dated 1574, marks this phase. The second phase, completed in the 1580s, saw a new range containing a great hall and chamber built on the north side of the courtyard. The second phase probably followed Robert"s acquisition of the Earldom of Orkney in 1581. After the death of Robert Stewart, the palace was used only occasionally by later earls of Orkney, and was not occupied after the mid-17th century. By 1701 the palace had begun to deteriorate badly.
The two-storey palace was constructed around a central courtyard and well, with large stone towers at three of the four corners. It was as much a fortress as a residence. Only the palace"s upper floors had large windows; the accessible ground floors were equipped with small openings and an array of gun-holes, from which musketeers could cover every side of the building.
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.
