There was no Muslim population in the Pendik and Kartal regions until thebeginning of the 20th century – except for civil servants – and therefore nomosque was built. However, in order to meet the needs of the increasing Muslimpopulation, it was decided to build a mosque in the region in 1908 during thereign of Abdulhamid II. However, due to political events, the mosque was built inthe name of Sultan Mehmed V.
The mosque was enlarged by adding reinforced concrete elements in addition toits original masonry structure.
With a decision taken by the Pendik Mufti Office in 1991, the mosque wasrenamed Hilmi Abbas Paşa Mosque;.
During the restoration work, the reinforced concrete parts added to the originalstructure were removed and an attempt was made to return the structure to itsoriginal state.
