Pammakaristos Monastery is located in Istanbul and dates back to 12th century. It consists of two small adjacent churches. After the conquest of Istanbul it had been used as women’s monastery. Greek Patriarchate operated here in between 1456-1586. 

In 1587 Pammakaristos Monastery converted into Fethiye Mosque and all frescoes were covered with plaster and lime. It was restored in between 1936-1938 and all plasters on frescoes were scratched out and they became visible then it was converted into a museum. Today museum can be visited every day except Wednesday in between 09:00-16:30.
