Sisak Cathedral was built in the 18th century and dedicated in 1765. The spire was built in 1760.
After an earthquake in 1909, the old Baroque facade was replaced with a Neoclassical facade, with details in the Art Nouveau style. The church was also damaged during the Croatian War of Independence.
On 5 December 2009 Pope Benedict XVI established the Diocese of Sisak. As a result, the parish church became a cathedral.

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.
