The former church of Hagia Irini (Saint Irene) on the grounds of the Topkapı Palace was first converted into an arsenal, and then, in 1869, into a museum consisting of two sections: Mecma-ı Esliha-i Atika (Collection of Antique Weapons) and Mecma-ı Asar-ı Atika (Collection of Antiquities). These two collections were known as Müze-i Hümâyûn (Imperial Museum), and a catalogue describing the objects on exhibit was published in French. The Museum of Antiquities was later moved to the Çinili Köşk (Tiled Pavilion) near the Topkapı Palace and opened to the public in 1881. The need for more space led to the construction of the current building and the inauguration, in 1891, of the Arkeoloji Müzesi (Archeological Museum). In 1917, the Eski Şark Eserleri Müzesi (Museum of Oriental Antiquities) was opened in a nearby building. Today, the three museums (the Archeological Museum, the Museum of Oriental Antiquities, and the Tiled Pavilion) are united under the administration of the İstanbul Museums of Archeology.
