The stone pentagram in the woods is shown in the opening shot, in 1692. Later, Nigel says, "It's actually a very powerful Wiccan symbol." The amulet is also from the 1600s. Wiccans do use the pentagram, but they could not have made either the stone pentagram or the amulet, as Wicca is a modern pagan religion that was only developed in England in the first half of the 1900s.
