Our hotel was opposite this cathedral so we looked at it all the time and were amazed by this flamboyant building. It's undergoing some external cleaning at the moment, so we didn't see it at its best but it is certainly worth visiting. If you are younger and more energetic than me you should probably pay the entrance fee and climb the tower for the spectacular views of Vienna. We went inside the cathedral after an exhausting day of walking round museums when our energy levels were low and we just went as far into the building as we were allowed without paying for a full visit. It was packed with other visitors all vying for the best positions to take photos. It was enough for me! This was where we saw the only beggar we came across in Vienna.
