St Collen's Church is a parish church in the town of Llangollen, Denbighshire, Wales. The first church on the site was founded by Collen in the 6th century. Nothing of this building remains. A new church was built in the 13th century, in the Early English Gothic style. This was developed in the succeeding centuries, and then almost completely rebuilt in the 19th century. The architect of the Victorian reconstruction was Samuel Pountney Smith, who retained little of the earlier church, with the exception of the tower. The churchyard contains the grave of the Ladies of Llangollen, Eleanor Charlotte Butler and Sarah Ponsonby, and their servant Mary Carryl, who lived at the nearby Plas Newydd.
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.
