Al-Muallaq Mosque was built in 1758 by the Arab ruler of Acre, Zahir al-Umar. It was built in a courtyard on the site of a structure commissioned by the Crusaders and which later became the gate to the Genoaese quarter of the city. Up until 1746, the structure was used as a synagogue by Acre's Jewish residents, called the Ramchal Synagogue. The Jews still owned the building when Zahir chose to transform it into a mosque, but compensated them with a different building located in Acre's Jewish quarter. Leftover features of the synagogue include the niche for the Holy Ark and inscriptions in Hebrew.
The mosque is positioned along the edge of Acre's Old City market, situated between Khan al-Umdan and Khan al-Ifranj, and is risen over the street. From the outside, the main indicators of the mosque are its low-lying dome and the round base of its former minaret. The mosque's entrance is located beneath the original minaret's base. This minaret was demolished by the municipality of Acre in 1950, citing a public safety risk. The body of the mosque is mainly constituted by a large, square-shaped prayer hall, A triple-domed portico precedes the prayer hall's entrance. Beside the prayer hall is a smaller room that is currently used as a library. A stairway beneath a covered entryway leads into the courtyard.
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.
