Today was another day full of adventures. In the morning we went and visited and explored and castle which included an amazing cathedral with beautiful stain glass. We explored the other building which made up the castle which were also full of detail. After that we had free time to explore the city and eat lunch on our own. This was very fun and nice to pick a restaurant and enjoy. After lunch and some more free time we got ready and headed to the opera. The opera was long but incredible talent in the people who sang. Today was a good day which included more walking and adventures. Tomorrow we will visit a concentration camp which should be very interesting but emotional. Today was a fun filled day.
