The first small Starhemberg castle was built by Ottokar III, Margrave of Styria between 1140 and 1145. At the time, the Piesting river was the border between Styria and the March of Austria. In 1192, Styria—and, thus, the castle—was acquired by the Babenbergs. The last Babenberger duke of Austria, Frederick II the Warlike, expanded and fortified the castle, leaving Starhemberg as one of the most important castles in Lower Austria in the 13th century. In wartime, the archives and the family treasure was hidden here, and were guarded by the Teutonic Knights.
After the Battle on the Marchfeld in 1278, the castle was acquired by the Habsburgs. In 1482, the castle was captured by Matthias Corvinus, king of Hungary. In 1683, the castle offered protection from the Turks to the surrounding population.
To escape a new roof-tax the counts of Heusenstamm around 1800 had the roof covering removed, as well as doors and window frames, beginning the decline of the castle. Around 1870, a large part of the great hall collapsed. Until the mid-20th century, the ruins were used for the extraction of construction materials by the local population.
In the spring of 1945 a unit of the Waffen-SS used the ruined tower above the chapel as an observation post. Russian artillery fire inflicted heavy damage to the walls.
In the second half of the 20th century a local organisation, Friends of the Castle Starhemberg, has sought to restore the ruins. Since 2007, the castle has been closed to visitors, for security.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
