Church-Mosque of Vefa is a former Eastern Orthodox church converted into a mosque by the Ottomans in Istanbul. The complex represents one of the most important examples of Comnenian and Palaiologan architecture of Constantinople.
The church was erected in the 10th or the 11th centuries. During the Latin domination of Constantinople after the Fourth Crusade the edifice was used as a Roman Catholic church. Shortly after the Ottoman conquest of Constantinople, the church became a mosque, founded by the famous Kurdish scholar Molla Gürâni. The mosque is also named after him. In the 19th century the mosque was badly damaged, possibly by the fire which in 1833 ravaged the surrounding quarter. In 1848 the complex was restored: in that occasion the mosaics which adorned the building were largely destroyed. In 1937, the building underwent a partial restoration, and its surviving mosaics were uncovered and cleaned.
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.
