King Alfonso II founded the Monastery of San Paio de Antealtares in the year 830. It fell into decay at the end of the 13th century, and in ruins, the Catholic Monarchs eliminated it and included it into S. Martín Pinario. In 1495, Gómez de Marzoa´s efforts to set up a college for poor students led to the monastery becoming Compostela´s first school and the origin of Galicia´s Renaissance University. The Order of benedictine nuns occupied it as of 1499.

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.
