Łomża Cathedral was built between 1504-1525 and inaugurated in 1531. According a legend there was a church near the current cathedral already in c. 1000 AD. After the cathedral was damaged in Swedish wars it was restored to Gothic Baroque style in 1691-1692. The southern sacristy was added in 1886. Łomża Cathedral was again damaged in Second World War and rebuilt between 1952-1958.
The most precious treasure in the cathedral is a painting of the Virgin Mary dating from the 16th century and crowned by Pope John Paul II in 1991. There are also beautiful Renaissance items like two tombs of local governors from 1575 and 1611.

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.
