Am Cobenzl, named (date unknown) after Philipp Johann Graf Cobenzl.
Johann Philipp, son of the k. k. Treasurer Guidobald (also Guido) Count Cobenzl, from the ancient Carinthian noble family Cobenzl, and Maria Anna Benigna, Countess of Montrichier grew up at their father’s Lueg Castle (today Predjama Cave Castle).
Philipp Graf Cobenzl, together with Count Joseph Colloredo-Mels, accompanied Emperor Joseph II on his trip to France from April 1st to August 2nd, 1777. Immediately afterwards he traveled to Berlin as an envoy, but was unable to prevent Prussia from entering the War of the Bavarian Succession impede. In 1779 he concluded the Peace of Teschen, which brought the War of the Bavarian Succession to an end. He was Vice Chancellor from 1779 to 1793, and from the end of 1792 State Chancellor as Kaunitz’s successor. Cobenzl had to hand over the management of the State Chancellery to Franz Maria von Thugut at the end of March 1793 due to failures in the second partition of Poland. After his resignation he became chancellor for the Italian provinces. Cobenzl was ambassador in Paris from 1801 to 1805.
In 1776 he acquired land on the Reisenberg (now known as Cobenzl) and had the Jesuit houses there converted into a country house. The garden designed by Cobenzl in the English style with numerous wooden structures was praised by his contemporaries. In 1809 parts of the complex were destroyed by the French army. In the 19th century and at the beginning of the 20th century, the former Cobenzl country house was converted into a castle. A later building is now known as Cobenzl Castle. In the 18th century, the count used the place to regularly invite contemporary artists. Among them was Wolfgang Amadeus Mozart, who felt strongly inspired by this place.
Count Johann Philipp von Cobenzl was the last of his family. He is buried in the St. Marx Cemetery.
A forced labor camp was located at Am Cobenzl between 1942 and 1945.
