In 1950 Canon Harry Cheales, parish priest of Wyck Rissington, a small village in the south of England, had a curious dream. In it, he was looking out of window of the rectory while below him, in the garden, he could see people walking around a maze. A shadowy figure behind him was describing the scene.
The dream was so vivid that, on walking, the rector felt compelled to build a real-life version of the maze he had seen. The newly constructed maze was modeled on a set of religious carvings in the village church and the design was symbolic. The winding pathways represented the journey of life. The wrong turnings and culs-de-sac symbolized the sins that people commit before death, obstacles on the way to paradise and heaven.

Very interesting read.
Most of them disapeared (some were just painted and got washed by the time) but you still can see a remarkable one in France in the cathedral of Chartres: http://www.crystalinks.com/labychartresfloor.jpg
Another great maze is the Peace Maze in Northern Ireland.
