Gates date back to the Bronze Age. However, simply put, as long as there was a fence or a barrier of some sort, then a point of access which can provide security when not in use was necessary as well. While gates existed in fortified walls, they also existed in the first fences built to pen domesticated animals. Over time, the style of gates changed as well as the hardware necessary to keep them not only usable but level as well. Whatever the style of gate, you can find gate hardware to meet your needs.
