What is the symbol of Lazio Italy?

Excuse me, could you please clarify something for me? I'm curious to know, what exactly is the official symbol or emblem that represents the Lazio region of Italy? Is there a specific design, crest, or icon that is commonly associated with Lazio and its heritage?
