City trip to Bamberg

This day we were visiting Bamberg, one of the most beautiful cities of Franconia. As soon as we arrived we were split into two groups. One group explored the city with an audioguide, the other group did it with a regular guide.
The first group could walk around the city freely and use the device to get information about certain sights: you simply come to an object and press a number on a screen, then the information is given to you through your earbuds.
The second group had to follow their guide but they got more personal and special information about Bamberg. Also they had the possibility to ask questions.
The guides showed us the beutiful parts of the city, like the Catholic cathedral, gorgeous gardens and the L shaped building, which has a crazy story behind it: the owner of a building wanted a U shaped one, but in the end he didn't have enough money to finish, so it ended up looking like the letter L.
After we all met again at the market place we had some free time. During that time we were devided into small groups and given a challenge to trade an apple with strangers for something more valuable. The results of this task were unexpected. Some of us traded it for a lighter, a pack of gum and even more valuable things such as Iphone cases, a charger, or for some wine glasses. It was exciting, because we needed to come up to random strangers and to bargain with them.
It was a wonderful day.
