The village church dedicated to Saint Mary Magdalene in Rennes-le-Château has been rebuilt several times. The earliest church of which there is any evidence on the site may date to the 8th century. However, this original church was almost certainly in ruins by the 10th or 11th century, when another church was built upon the site - remnants of which can be seen in Romanesque pillared arcades on the north side of the apse. This survived in poor repair until the 19th century, when it was renovated by the local priest, Bérenger Saunière.
The village received up to around 100,000 tourists each year at the height of popularity of Dan Brown's bestselling novel The Da Vinci Code. The modern reputation of Rennes-le-Château rises mainly from claims and stories dating from the mid-1950s concerning the local 19th-century priest Father Bérenger Saunière. These stories influenced the authors of the worldwide bestseller The Holy Blood and the Holy Grail in 1982, and that work in turn influenced Dan Brown when he wrote The Da Vinci Code, published in 2003.

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.
