Built at the beginning of the 19th century, the original Schloss of the Baroness von Stolzenau was surrounded by a large park.

Keczendorff, as Ketschendorf was first known around 900 years ago, was an undefended village outside the city walls of Coburg on the western slope of the Buchberg.

[1]: 39 In 1802, the Duchess Augusta, wife of Francis, Duke of Saxe-Coburg-Saalfeld, bought the properties on which the Schloss and the park are located today.

Even Frederick Louis, Hereditary Prince of Mecklenburg-Schwerin, and the parents of Constantine, Paul I and Sophie Dorothea of Württemberg, as well as his brother, Tsar Alexander I of Russia, were guests at the castle.

Born in Paris in 1815, Victorine Noël had already been, for the last 22 years, a celebrated opera singer with the stage name of Rosine Stoltz.

The then reigning Duke of Saxe Coburg and Gotha, Ernst II, was not only a friend of artists and singers, but also composer of the opera, Santa Chiara.

Her great wealth enabled the freshly ennobled Baroness to acquire Schloss Ketschendorf with the adjoining park grounds for 100,000 francs, allegedly for her illegitimate son Charles, whose father, according to the Baroness, was none other than Napoleon Bonaparte and who could now style himself as Karl Freiherr (Baron) von Ketschendorf.

Inside the building the staircase was formed with decorative cast-iron railings and the view, with the tracery of the cathedral windows, is representative of the south side of the castle's centre.

In 1872, the American William Tilden acquired the property and sold it in 1873 to the Kommerzienrat Karl Rudolf Epner from Berlin.

In 1940, it came under state administration through foreclosure because of the alleged debt of 145,000 Reichsmark in Reich Flight Taxes and the expulsion of the Jewish family Mayer.

The town of Coburg bought Schloss Ketschendorf at auction, for 45,000 Reichsmark, including the park and furnishings, and set up a shelter for German repatriates from Bessarabia.

The family property was returned in 1954 to Egon Freiherr von Mayer by the way of Wiedergutmachung (reparation) but he did not move back to Ketschendorf.

The castle's park, now open to the public, was greatly expanded in 1868 at the construction of the new Schloss with some newly acquired land.

As a replacement for the no longer accessible community fountain, the Baroness donated the Karlsquelle, named after her son, to the Wassergasse, next to the former forge.

It was eventually sold in 1959 to the Sportverein Ketschendorf, which converted it to a training hall for weightlifting and a clubhouse and in 1995 added to the club a large open terrace at the pond.

[1]: 39  On 1 January 1990, the responsibility for the architectural preservation, construction and renovation of the castle, which began in 1979, was passed to the DJH-Landesverband but a part of the historic park, equipped with areas for games, sports, meadows and ponds, remained with the town.

The Altes Ketschendorfer Schloss, the villa in the Oberen Klinge, received two awards in 2005 for its exemplary and detailed efforts of preservation during its expansion.
