The Herz-Jesu-Kirche is the largest church in Graz. It was designed down to the last detail by architect Georg Hauberrisser and constructed from 1881 to 1887.
The church was designed in the Neogothic style, with a large, high nave and under-church. The tower is 109.6 meters tall, making it the third-highest church tower in Austria. Of special note are the stained glass windows, which are among the few extant examples in Austria of Neogothic stained glass.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
