The vaulting never caused a problem but, in 1590, the tower collapsed, destroying the choir, which had just been completed. In response to the disaster, the Duke decided that bad omens dictated a need for an even larger church so he added to his original plans.
Shortly thereafter, construction began on the second phase of this colossal church, lasting until its completion in 1597. During this time, a new and grander choir was built as well as a transept, which was an addition to the original drawings.
A number of bronze statues grace the beautiful façade of the church, including a large statue of Michael the Archangel situated between the two main doors.
