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:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
