Caldicot Castle is an extensive stone medieval castle, built near the site of Harold Godwinson's former Saxon castle by the Norman earls of Hereford from about 1100. Humphrey III de Bohun was the probable builder, in about 1170, of the stone keep and curtain walls of the present-day castle. The Bohun family held the manor and castle of Caldicot for more than two centuries, over eight generations.
In 1381, Essex was convulsed by the Peasants' Revolt. This may be why Thomas decided to spend part of that year in Caldicot. During his stay he gave orders for major new work to be done on the castle. A new gatehouse and drawbridge were constructed. At the rear of the castle a dovecote was replaced by a new tower with private chambers, now known as the Woodstock tower. At the foot of the Woodstock tower two carved stones were to be placed, one marked 'Thomas' the other 'Alianore'.
In the 16th-17th centuries Caldicot Castle was evidently neglected, fell into ruin and became little more than a farmyard. In 1964, Chepstow Rural District Council bought the castle. The building, including a small museum, was opened to the public in 1965.
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.
