This is an annotated translation of what is perhaps the most important Ottoman literary source for the architectural monuments and urban form of the Ottoman capital, Istanbul: Hafiz Huseyin bin Ismail Ayvansarayi’s Hadikat al-Cevami (The Garden of Mosques). There are also separate descriptions of each of Istanbul’s more than 800 mosques, plus accounts of its medreses, tombs, tekkes and other pious foundations.
