Gülhane Park (Turkish: Gülhane Parkı, "Rosehouse Park"; from Persian: گلخانه Gulkhāna, "house of flowers") is a historical urban park in the Eminönü district of Istanbul, Turkey; it is located adjacent to and on the grounds of the Topkapı Palace. The south entrance of the park sports one of the larger gates of the palace. It is the oldest and one of the most expansive public parks in Istanbul.
The namesake of the park, the Gülhane ("Rosehouse") present on the grounds, was the place where the 1839 Edict of Gülhane (Turkish: Tanzimât Fermanı or Gülhane Hatt-ı Şerif-î) was proclaimed. The edict launched the Tanzimat reforms in the Ottoman Empire, which modernized the empire and included changes such as the equalization of all Ottoman citizens, regardless of religion, before the law. The proclamation was made by Grand Vizier Mustafa Reşid Pasha, a leading statesman, diplomat, and reformer in the Empire.
The old barracks within the area of Gülhane is expected to be converted to a cultural center in due course; the center will host a library and exhibition hall together with a workshop on kilim and handicrafts.
