Saint Kilian
Beginning in 1237, the city seal depicted the cathedral and a portrait of Saint Kilian, with the inscription "SIGILLVM CIVITATIS HERBIPOLENSIS". It shows a banner on a tilted lance, formerly in a blue field, with the banner quarterly argent and gules (1532), later or and gules (1550). This coat of arms replaced the older seal of the city, showing Saint Kilian, from 1570.
