Dialogue 3.8.4-5
In the village of Amboise, the old fortress that is now inhabited by crowds of brothers, you know that there was the temple of an idol, constructed on a large scale. With the smoothest stones, the massive structure was built up into turrets, which, rising to a lofty point, was preserving superstition in that place because of the impressiveness of the craftmanship.
The blessed man had often commanded Marcellus, who had taken position of presbyter there, to destroy the temple. Returning after a short amount of time, Martin scolded the presbyter, asking why that structure devoted to an idol still stood. He offered as his excuse that it would be virtually impossible to tear down such a great structure with a band of soldiers and the power of multitude of people; so why should Martin so readily believe that it could be attended to by feeble clerics and infirm monks? Then Martin returned to his well-known resources: he remained in prayer throughout the entire night. In the morning, a storm arose that leveled the idol's temple, right down to its foundation. Let Marcellus confirm these words!
