Haverfordwest Priory was a house of Augustinian Canons Regular on the banks of the Western Cleddau. The priory was first mentioned around 1200.
At the time of Henry VIII’s Dissolution of the Monasteries (1536–1541), it was acquired by Roger and Thomas Barlow, brothers of William Barlow, bishop of St David's.
From 1983 to 1996, the site (now under control of Cadw) was excavated and the outlines of the buildings are visible. Much architectural material of a high standard was discovered and can be seen in Haverfordwest museum. Also unearthed was a unique medieval garden with raised beds.
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.
