Abdurrahman Ağa Mosque

Abdurrahman Ağa Mosque, Silahtar Abdurrahman Ağa Mosque or Paşalimanı Mosque, a historic mosque from the Ottoman Period located in the Sultantepe Neighborhood of Üsküdar district in Istanbul. It was commissioned by Abdurrahman Ağa, the armorer of Sultan III Mustafa. Construction of the mosque began in 1765 and after a one‑year building process it was opened for worship in 1766. Architecturally the mosque reflects Ottoman influences.

The mosque, which fell into ruin over time, was repaired in 1832 by Mahmut II. It was repaired again in 1995.

It was originally built as a mosque in the original plan. Later a tekke was added. The mosque is situated on a street level. The area where the mosque stands was referred to as Hacı Hesna Hatun Neighborhood up to the 2008 regulations.

For the mosque that had become deformed over time, restoration works that began with a restoration tender by the General Directorate of Foundations on 19 July 2016 were planned to be completed in 2017. The restoration works aim to preserve this historic building in accordance with its original state.
