Aiming stone

An aiming stone (Turkish: nişan taşı or nişantaşı), also named in English target stone or range stone, is an inscribed stone stele erected in the Ottoman age to mark a record in archery (and later rifle or other weapons) shooting. When erected by a high dignitary or a sultan, the stele bears often an artistic and literary significance. While about three hundred such stelae existed in Istanbul at the end of the Ottoman Empire, only about 40 are still extant today.
