The Riddle Age 

This is a tour of the Cathedral with an explanatory part that goes around its exterior up to its façade.

In front of the façade, the participants are given a series of four riddles which they have to analyse and explain to their other participants after they are divided into four different groups.

A spokesperson is appointed to explain the hypothesis each group has come up with to solve their riddle.

The activity ends by sharing all the riddles.
