Smith's Bible Dictionary

Tower Watch-towers or fortified posts in frontier or exposed situations are mentioned in Scripture, as the tower of Edar, etc., (Genesis 35:21; Isaiah 21:5; Isaiah 21:8; Isaiah 21:11; Micah 4:8) etc.; the tower of Lebanon. (2 Samuel 8:6) Besides these military structures, we read in Scripture of towers built in vineyards as an almost necessary appendage to them. (1 Samuel 5:2; Matthew 22:33; Mark 12:1) Such towers are still in use in Palestine in vineyards, especially near Hebron, and are used as lodges for the keepers of the vineyards.
