The Cathedral is a three-aisled basilica.
In the middle between the nave in the east and the choir to the west, the transept is crossing.
Above the crossing the dome is a round, light-flooded Tambour. At the chorus, the two high bell towers are added.
The portal is designed as a porch on the east portico like a Greek temple.
The cache was placed outside of the cathedral in 11/2014, but was not published.
Nevertheless there were two founds in the log-book, so that the FTF is already fixed for Vajda Fermas and Accent circonflexe.
Gratulations to them and good luck finding the cache for all the others !
