Blois Cathedral (Cathédrale Saint-Louis de Blois) is a Roman Catholic cathedral, and a national monument of France, in Blois. It is the seat of the Bishopric of Blois, established in 1697.
This was previously the collegiate church of Saint-Solenne, the original building of which dated from the 12th century. Apart from some traces in the crypt nothing survives of this. The façade and the bell tower were built in 1544. The nave was destroyed by a hurricane in 1678, and the reconstruction in Gothic style took place between 1680 and 1700 under the architect Arnoult-Séraphin Poictevin (d. 1720). The Lady Chapel by the architect Jules Potier de la Morandière was added in about 1860.
To celebrate the church's elevation to a cathedral in 1697, Louis XIV presented the organ loft in 1704. The new see thereupon took the dedication to Saint Louis.
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.
