In the ancient world, towers were built to protect crops, roads, and cities. They were used both domestically to watch over a landowner’s fields and militarily in the defense of a city. Watchmen stood in towers, armed and ready to sound the alarm if enemies threatened their territory. The more towers a city had, the stronger it was thought to be (see Ps 48:12-14). The tower at the center of a city would have also served as a storehouse.
