What is a lightning rods how do they functions?

An example is a metal rod fixed to the top of a church steeple. The rod will protrude above the tallest point of the building. There will either be a metal strap or a thick cable connecting the rod to the ground, with the bottom end buried beneath the ground surface. The principle is that should a lightning strike occur, instead of damaging the building's structure, the lightning will strike the rod and the electricity will be directed down the strap or cable and into the earth, so saving the building from damage.
