Perhaps you have heard the french
word for Grail( GRAAL) is present in the church of Rennes. It can be read by selecting the
first letter of certain statues's name :
-St Germaine
-St Roch
-St Antoine de Padoue
-St Antoine
-St Luc (on the pulpit)

If one draws a line linking all
these statues, it makes a big M under Mary Magdalene's statue.
