On the initiative of the Prince Bishop, the construction of the "Neues Schloss" (New Palace) was begun in 1710. The "Altes Schloß" (Old Palace) no longer satisfied the representation requirements of the baroque Prince Bishop. In the course of the construction work Stauffenberg's interest appears to have failed, and he only had the building completed inside as a chancellery. Stauffenberg was unable to settle an old inherited burden, the miserable economic situation of the bishopric of Konstanz. In addition, he was also partially responsible for the fact that no improvement resulted, as he had doubled the size of the staff at the court in Meersburg.
Schönborn was a Cardinal and since 1722 "Koadjutor" (Coregent) in the bishopric of Konstanz. This position meant the succession to the office of the ruling prince bishop. In addition, Damian Hugo von Schönborn also held the office of the Prince Bishop of Speyer. His family was among the dynasties of the age which found the greatest pleasure in building. Schönborn himself had his residence in Bruchsal built during his term of office as Prince Bishop of Speyer.
He too was not satisfied after taking office as Prince Bishop in Meersburg with the Old Palace and the incomplete "Neuer Bau" (New Building). As a result, he accelerated the plans to complete the interior of the New Palace and engaged Balthasar Neumann (1687-1753), who designed the staircase. Schönborn had the former riding stables torn down and a chapel erected in their place.
His death in 1743 prevented further rooms from being decorated. His portrait is immortalized in the ceiling painting of the chapel.
Franz Conrad von Rodt was descended from knightly nobility and began, following thorough studies in Freiburg, Rome , Sienna and Strasbourg, a career in the "Reichskirche" befitting of his rank.
This prince bishop carried the completion of the New Palace to its conclusion. His portrait can be found in the ceiling fresco of the staircase, "May the land of the Prince Bishop blossom under the favor of divine Providence". Here Rodt is presented by the personification of Glory and History.
The brother of Franz Conradt resided in the New Palace, where he had the interior redecorated and purchased new furnishings in the taste of that era. This prince bishop was an enthusiastic collector of natural history specimens, with a particular interest in shells. His collection in Meersburg was so famous that many visitors came to the bishop's city for this reason alone. Like his brother, Maximilian von Rodt ruled for 25 years and was clearly overshadowed by his predecessor.
