The Church of All Saints, also known as Holy Cross Church (Kreuzkirche) was built in 1478 by Jörg von Halsbach and was the first church with a cemetery in the St. Peter parish. It was once located at the crossing of four roads, whence the original suffix am Kreuz ('at the Cross').
It has unadorned brickwork walls, Gothicvaults and a tall bell tower. The interior was rebuilt from 1620 in Baroque style, the only remaining Gothic elements being the nave's vault, fragments of a fresco and a Crucifix by Hans Leinberger. The tomb of banker Gietz and the Apparition of the Virgin to St. Augustine (by Hans Rottenhammer) are in Mannerist style.
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.
