Cordóba

Cordoba is known for its unusual cathedral, which mixes Arab, Christian and Jewish elements. Although you may find it uninteresting from the outside, you'll change your mind when you try to walk around it. It's huge. And once you enter and fall through it.
Its silhouette from a distance is also worth seeing - look at it from the other side of the bridge. 

If you like a bit of an adrenaline rush, we recommend taking a carriage ride. The streets are so narrow that you'll barely get through, the dodging pedestrians don't throw the carriage off its stride in the slightest.
