During the medieval period within the propugnaculum of the Iron gates, existed a kind of an open air court room for the minor criminals. The medieval time tales do not stop here.

It is the last surviving, among the four built on the top of each gates, that, according to a legend, for a long time served as the pilgrimage place for the pregnant women, who, in order to keep their pregnancy safe climbed up to lit a candle.
