Shields on the Rödertor

Town Emblem Shields for the Free Imperial City of Rothenburg ob der Tauber

Most to the gates and towers display the shield with two red towers for Rothenburg ob der Tauber while the black eagle on a yellow background is for the Holy Roman Empire to indicate visitors enter a Free Imperial City, which Rothenburg was from 1274 until it was absorbed by the Kingdom of Bavaria in 1802. (The double-headed eagle was only in use after 1433.)
