The spot where two roads meet in a cross as opposed to a junction used to be considered a magical place. In times passed, people would bury charms at crossroads depending on what they wanted to wish for, a horseshoe was a popular item to bring luck for example.
The symbolism of a crossroad is understandable - north, south, east and west or the four winds are represented. People have been ritually buried at crossroads, and in some countries still are today. Those who have committed suicide or the mentally ill have been known to be buried at these sites.
In Scotland it was thought if one sat on a crossroad on a three-legged stool on Halloween (Samhain) at midnight, those who will die in the next year will be visible.
