The Broch of Borwick is an Iron Age living structure. It has an external diameter of 17 metres and an internal diameter of 8 metres. The walls which are 3.5 to 5 metres thick currently stand to a maximum height of 2.6 metres. The eastern half of the broch and the entrance passage are well preserved, but the western half has been destroyed by erosion. The entrance passage, which is still lintelled over, is 5.6 metres long with door-checks each formed of a slab set on edge 3 metres from the outside. A guard cell opened off the right of the passage.
The broch was once cut off from the flat land beyond by an outer wall, and there were outbuildings between the wall and the broch.
The site was excavated in 1881 by W. G. T. Watt, and the interior was cleared of debris. Ashes, bones and shells mixed with clay were found under the rubble. Beneath this was a layer of small flat stones and under this the broch floor. Finds included several combs, a small whale vertebra cup, a spindle whorl, a stone gaming piece, a whetstone, hammerstones, some stone knives and choppers, an iron rod, and some querns.
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.
