This is a labyrinth-like city, gps often lose its role in this unpredictable laneway, and the same houses and roads will also make you lose the passion to continue exploring. I stayed for 2 nights, except for the castle, the rest of the time is lingering in the vegetable market, Between various snacks and wine restaurants, when writing travel notes to consult relevant information, I suddenly found that there are many perspectives on the castle pictures on the Internet that I have not seen.
