Saint Gertrude's was an Augustine abbey, limited to 12 canons of noble descent. The church was built from the 14th to the 16th century. The tower has an openwork spire, dating from 1453. Inside is an 18th century carillon.
The abbey was closed in 1796 (during French occupation) and the buildings got other uses. In 1919 it became a Benedictine abbey. Reconstructions were carried out after the fire during World War II. The abbey grounds (compound outside the church) at present has mixed uses, and is like a little pleasant park to hang out or have a quiet rest.
During the second world war, the church (as many others in Leuven) was seriously damaged. The artistic choir stalls seemed beyond repair. Fortunately photographs existed. After the war, the stalls were recreated by sculptors, who did an excellent job. The choir with its many wooden sculptures is now one of Leuven's most outstanding works of art. One can distinguish between original parts and later parts by judging the colors of the wood, the older parts being darker.
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.
