The history of the area goes back to the time of the Celts and the Romans. The unique lapidary (collection of Roman stone monuments) on the outer wall of the upper floor of the castle bears witness to this.
Seggau Castle was the representative seat of the Styrian bishops until 1786 and also their summer residence until the 20th century. For many centuries the castle served as an ecclesiastical property to provide income for the bishop of the Diocese of Seckau and support him in his representational duties. It was also an important employer for the region and a meeting place for numerous functions.
The High C astle was built by the archbishop of Salzburg (Conrad I) as a mission and administrative bastion from the 11th century and enlarged by the bishops of Seckau from 1218 on. It is home to a number of outstanding artistic treasures.
The so-called "Prince Bishop's Rooms" are among the castle's most impressive. Located on the second floor of the High Castle, these representational rooms of the prince-bishops with their baroque furnishings are artistic jewels known far beyond the country's borders.
"Seggau Castle" is also home to the largest historical bell in Styria: the so-called "Seggauer Liesl". It is still rung by hand at 12 noon on Sundays and public holidays. The baroque Lady Chapel and the modern Chapel of St. Michael with works by contemporary Styrian artists provide a fascinating juxtaposition of past and present.
