[1] The medieval history of this area begins with the old Moravian fortification in the Sand location, near Burg Raabs.

Prior to being overthrown by the Hungarians, the Great Moravian Empire ruled today's Lower Austria, up to Enns river.

The first written records related to the lord of the castle "Gotfridi in castrum Racouz" is in Bohemian Cosmas Chronicle from 1100.

Instability in South Moravian space in the first half of the 11th century led to repeated conflicts.

For example, in the Altahensis annales it is recorded that in 1082 the son of Margrave Adalbert took one of the towns at the present northern provincial border after it was forcibly taken from his father by the Přemyslids.
