Easton's 1897 Bible Dictionary:

Gibeah
   a hill or hill-town, "of Benjamin" (1 Sam. 13:15), better known
   as "Gibeah of Saul" (11:4; Isa. 10:29). It was here that the
   terrible outrage was committed on the Levite's concubine which
   led to the almost utter extirpation of the tribe of Benjamin
   (Judg. 19; 20), only six hundred men surviving after a
   succession of disastrous battles. This was the birthplace of
   Saul, and continued to be his residence after he became king (1
   Sam. 10:26; 11:4; 15:34). It was reckoned among the ancient
   sanctuaries of Palestine (10:26; 15:34; 23:19; 26:1; 2 Sam.
   21:6-10), and hence it is called "Gibeah of God" (1 Sam. 10:5,
   R.V. marg.). It has been identified with the modern Tell el-Ful
   (i.e., "hill of the bean"), about 3 miles north of Jerusalem.
