Historical comments about the place:

The cathedral was built in Romanesque style in Trento Trieste square, at the beginning of 12° century and, at the end of the century, it was transformed and decorated in Gothic style in the facade.

The proportions of the building are very interesting and they transmit a sense of order and harmony. Inside the triangular tympanum there is an almond with Risen Christ, ancient symbol of the union between heaven and earth.

Maths imply in it: Equilateral triangle and his properties.
