Charlottenhof Palace or Charlottenhof Manor (German: Schloss Charlottenhof) is a former royal palace located southwest of Sanssouci Palace in Sanssouci Park at Potsdam, Germany. It is best known as the summer residence of Crown Prince Frederick William (later King Frederick William IV of Prussia). He charged the architect Karl Friedrich Schinkel with the remodeling of an already existing farm house and the project was completed at low cost from 1826 through 1829. In the end, Schinkel, with the help of his student Ludwig Persius, built a small Neoclassical palace on the foundations of the old farm house in the image of a Roman villa. (wikipedia.org)
