The old city bridge tower is at the end of the Charlie Bridge, the entrance of the old city to the Charlie Bridge. We walked all the way from Prague Castle to Charlie Bridge and back to the old city, so it was after Charlie Bridge that we saw this beautiful Gothic tower. The Powder Tower in the old city of Prague is also modeled after the old city bridge tower. The grey and black walls of the old city bridge tower have the national emblem and five statues of that time, which are well preserved. You can also climb the bridge tower and enjoy the Charlie bridge panorama and beautiful city scenery.
