Lion's Head Door Knockers
Some historians believe this emblem could have something to do with a particular clan or dynasty and others or that the lion's head performs the functions of a guardian, much like the statues of lions found all over Italy.

The lion has been used as symbol and is thought to signify strength, pride, protection and power. A Lion's head door knocker acts a guardian to the home.
