Mehmed Paša Sokolović's Fountain is an Ottoman era fountain in Belgrade. It is located next to the Defterdar's Gate near the northwestern wall of the Upper Town of Belgrade Fortress. Evliya Çelebi states that the fountain was erected in 1576/77, during the lifetime of Grand Vizier Меhmed Paša Sokolović and it is his only surviving endowment in Belgrade. The precise position of the fountain does not appear in any cartographic sources until the 17th century. The earliest sketch dates back to a plan from the National Library in Paris from the early 17th century, in which the fountain was presented as a rectangular structure with three free sides.
