The Wieliczka Salt Mine and especially the St. Kinga’s Chapel 101m below ground level are exceptional. A huge room (465m² and 11m high) so deep underground, enlightened by chandeliers and ornamented with numerous pieces of art. But the most impressive for me was the several hundred years old altar made from salt.
I was a bit baffled when I crossed the Castel Vecchio Bridge (Ponte di Castel Vecchio or Ponte Scaligero) and saw rubber rafts on the Adige. Rafting in the middle of the city? It seems possible in Verona and is certainly also an interesting way to discover the town from a different angle.
The Wieliczka Salt Mine must make it on your list when you have a rainy day in Cracow. The mine is simply mind-blowing. There are 300km full of statues, arts and chapels on 9 levels that were built over the last 700 years. It is the oldest salt mine of its kind in Europe and since 1978 legitimately among the first UNESCO World Heritage Sites.
