In this Latin written document King Koloman confirmed the property as belonging to the Benedictine monastery of St. Hypolita in the upper Nitra. Originally the fortress was made from wood and grew out of the older fortress. Gradually over the 13th century it was built up from stone as property of the Poznanovec family.

El Escorial is situated at the foot of Mt. Abantos in the Sierra de Guadarrama.
