There is a walkway-like structure that is made to represent a river, and the tower is supposed to be a tree!
We're going to Portugal next week! I'm super excited and really looking forward to seeing a new city in Portugal and hearing Portuguese again. That, and I'm already hungry for Portugal's famous egg pastries! The thing I look forward to the most is the famous library that is said to have inspired J.K. Rowling when she was writing about the stairways in Hogwarts. Fun fact: Rowling lived in Porto for a few years!
