Krakow was the capital of Poland in the Middle Ages, and its historical centre has remained unchanged since then. That's why Krakow attracts a lot of tourists – it will be much more interesting than Warsaw for those who want to see the ancient Polish city. Krakow is very cozy, and it can set a high standard for other tourist centers in Europe, and a tour of it won't be so expensive – prices in Poland are quite reasonable.
It's very convenient to visit Krakow with sightseeing tour: the main sights are concentrated in the Old Town, it is small, so you can walk around all the interesting things. It is possible to do it even in a day, though it is better to set aside some days for detailed acquaintance with the whole city.
The main sights of Krakow:
Krakow's Main Market Square is very large and contains a lot of interesting things: for example, in the evenings there can be puppet shows in one part of the square, while at the same time there are fire shows or other similar events in the other part. Because of the size of the area, they do not interfere with each other.
The Sukiennice Trade Rows and the Town Hall Tower in the centre are of particular interest here – they used to keep prisoners in its dungeon, but now it's a museum. It would be very interesting to visit it with a private guide. As well as the main attraction in Krakow, the Wawel Castle. This is a whole complex of very beautiful buildings, the corridors of which are simply breathing history – they do personal excursions in English. Legend has it that a dragon used to live in a cave near the castle.
