The wall surrounding the former Old Town of Krakow was standing in perfect condition for a long time, but in the start of the 19th century most of the walls were torn down. Today only trees can be found in the areas of the former wall surrouding the Old Town, except from the area by the Florian Gate. Togeter with the gate itself, you can see parts of the wall directly connected to the gate.
In the old days there were eight such gates that led into the town, all guarded and with drawbridges. The Florian gate was built in 1307, and it was named after one of Krakows guardian saints, Saint Florian. The Florian gate was were the royal way that led to the Wawel Castle started, and from there it led towards the Main Market Square, just as you are able to walk today as you enter into Krakow through the Florian Gate.
