The Market Fountain from 1595 shows St. Peter, the patron saint of the Cathedral as well as the city, standing on top, surrounded by the four cardinal virtues of good city government, Justice, Strength, Temperance, and Wisdom (originals in the Municipal Museum), but also by monsters and frolicking monkeys. The fountain, just like the Cathedral and the parish and guild church St. Gangolf as well the Steipe, are all rooted in the 300-year struggle for supremacy in the city. Between the 10th and 12th centuries the Trier archbishops became both the ecclesiastical as well as the secular rulers.
