The present day Basilica goes back to the 12th Century and was designed on the model used for the cathedral in Novara. Quite apart from its very fine frescoes, do not miss the extremely rare and precious pulpit carved in green marble, supported by 4 much older columns. The undeniable charm and fascination of the island are not its sole attributes, it is just a little mysterious too, thanks to the presence of the Mater Ecclesiae Benedictine convent where there are now about 80 nuns living when in 1973 there were only 6. They live in total silence.
