In 1668, the Dutchman Langelaer laid out an avenue starting from the west side of the City Palace running parallel to its ground plan, which originally ran all the way to Golm. Starting in 1671, this avenue was built out to the Neustädter Tor - New City Gate as "The Elector's Privilege".
Only in 1721 was the section leading to the Neustädter Havelbucht (New City Havel River Bay) added. Frederick II had imposing, representative houses constructed along this avenue, which had already been named Breite Straße - Broad Street - by that time. Some façades of these houses were actually sketched by the King himself. Parts of Breite Straße were destroyed in 1945. Finally, in 1972-73, the street was lengthened to link up with the Zeppelinstraße, by means of filling-in sections of the Neustädter Havelbucht.
"But what do I see here? Right against the palace are the royal stables, / Worthy to be looked upon, / In that it is not the architecture alone to be enjoyed, ...."
Bellamintes' report dates back to a time when Frederick William I had converted an orangery into stables.
In 1685, Elector Frederick William had an orangery built next to the City Palace, the so-called Pomeranzenhaus (house for bitter oranges), as the winter quarters for his plants from southern lands. In 1714, when a section of the pleasure ground was transformed into a drill field, the orangery was also affected. Bellamintes had once sung the praises of "horses so adroit" sheltered here, that it was "as if they would have wings at their feet".
Frederick II left it as a royal stable, but had it rebuilt in 1746 and lengthened by one third. Up until 1922, the building was used as a stable. A garrison museum and exhibitions of the Potsdam arts association were later housed here. Heavily damaged during WWII, the makeshift repairs allowed the former royal stables to become the home and exhibit rooms for the town museum. In 1977, extensive restoration work started, which skilled Polish construction workers carried out. The Royal Stable then became the Film Museum, which it remains today.
