Ort castle was founded around 1080 by Hartnidus of Ort, and improvements continued to be made into the thirteenth century - for example by Hartnidus V in 1244. In 1344 the brothers Friedrich and Reinprecht I of Wallsee purchased the castle, which became Friedrich’s sole possession on January 25, 1350. The castle remained in the possession of the Wallsee family until 1483, when Schloss Ort passed to Frederick III, Holy Roman Emperor.
From 1484 to 1491, the castle was governed by Gotthard von Starhenberg, the Governor of Upper Austria. In 1492, Bernhard of Starhenberg and later his descendants ruled the castle until 1584. In 1588, the castle was purchased by Weikhard Freiherr of Pollheim, but he sold the castle on April 6, 1595 to the city of Gmunden. However, Gmunden sold the castle to Rudolf II that same year. The castle then passed to other owners before finally being acquired by Leopold I, Holy Roman Emperor.
In 1876, the castle was acquired by Archduke John Salvator of Austria (John of Tuscany) (1852 – ca. 1911), but on October 6, 1889, he renounced his title and connections to the Habsburg imperial house and changed his name to Johann Orth, the tenth and last child of Grand Duke Leopold II of Tuscany and Maria Antonietta of the Two Sicilies departing for South America in 1890 with his morganatic wife on his own ship, the St. Margaret. Johann Nepomuk Salvator was presumed lost at sea in 1890, and declared dead in 1911, but his actual date of death is unknown.
The castle was acquired by Franz Joseph I of Austria in 1914, and it was intended for students of Gmunden’s schools to be allowed to visit the castle, but this plan was interrupted by World War I.
At present the castle is being used for a study center of the Federal Ministry for Land and Forestry. On January 5, 1995, the castle was officially acquired by the city of Gmunden.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
