The last station on June 3, 2011 on tour B of the Dutch Maze and Labyrinth Symposium 2011 was the chapel Our Lady in a great hospital at Amsterdam.
The labyrinth of type Ravenna lies in the entrance area of the chapel built by architect Ba Molenaar in Roman style. It is very difficult to recognise, because it is marked only by roughened lines in the otherwise smooth floor from rectangular sandstone flags. According to incidence of light and point of view one can see the pattern. The engraved surfaces show the way. Most visitors will not note it probably at all. Besides, the lines are very small, so that it is hardly suitable for walking.
