Eyüp Sultan Mosque, located in Istanbul's Eyüp district, is one of the city’s most sacred Islamic sites. Built in 1458 by Sultan Mehmed II, it marks the burial place of Abu Ayyub al-Ansari, a companion of Prophet Muhammad who died during the first Arab siege of Constantinople in the 670s.
The current mosque, rebuilt in 1800 after earthquake damage, reflects classical Ottoman architecture with later Baroque decorative elements. The complex includes a mausoleum, minarets, and is surrounded by the tombs of many notable Ottoman figures.
The mosque played a key role in Ottoman coronation rituals, where sultans were girded with the Sword of Osman. It remains a major pilgrimage site and a popular spot for Ramadan iftar meals and circumcision ceremonies.
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.
