The Fortress of Brod was constructed between 1715-1780 by the Archduchy of Austria to create a defense against the Ottoman Empire. The city of Slavonski Brod was an important strategic and traffic center controlling the border crossing towards Turkey and connecting main commercial trails at the time. The regular star-like form of the fortress was determined by the flat-country. It was built of rammed earth, bricks, wood and partially stone, and designed for the accommodation of 4,000 soldiers, mostly infantry and 150 cannons.
The Fortress of Brod was constructed according to the Vauban system. It is basically of a rectangular form, while the system of defense channels provides its star-like layout. It consisted of three defense zones: internal, external and southern, and it was protected by two moat areas, water-fed from the nearby stream.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
