What is "hananeel"

Tower Hananeel (or Hananel; hanan'e-el, chanan'-el, " El (God) is gracious") is a tower in the walls of Jerusalem, adjoining the tower of Meah (or Hammeah; "the hundred") to the east connecting to the "sheep gate" (Neh 3:1; 12:39). It is located on the northern wall section of the old city, near the Northeast corner, a point of the city always requiring special fortification and later the sites successively of the Baris and of the Antonia.
