1. The Great Barbican in Krakow is a historic fortification that was built in the 15th century to protect the city’s entrance from potential invaders. It is one of the few remaining parts of the city’s medieval fortifications and is a popular tourist attraction. The Barbican is located at the northern end of the Old Town and features seven turrets, a drawbridge, and a moat. Interestingly, the Barbican was never used to defend Krakow as no enemy army ever managed to breach the city’s walls during its time of use.
