The S. Martino collagiate appears like a scene of theatre through narrows streets.

                      The church has an high ( 37 mt ) and sumptuous facade.

On the facade piks a fanciful portal with the sculpture " S. Martino and the poorman ".

There are statues of S. Pietro, S. Paolo, S. Giuseppe and S. Giovanni Battista on the low facade, while there are statues of S. Martina and S. Comasia on the upper facade.

A very innovative architectonic element is the loggia for benedictions in the middle of the church's facade.

The bell-tower, in romanesque-gothic style, stands from one side of the church.
