The Brandenburg Gate has twelve columns, six on the entrance side and six on the exit. The columns form five roadways, citizens originally were allowed to use only the outer two. This is rather like Admiralty Arch in London, the central roadway is reserved so that royal and important traffic is not delayed. On top of the gate is the Quadriga. This is Viktoria, the goddess of victory driving a Quadriga, a type of horse-drawn chariot.
