The Kraków Barbican is a fortified outpost once connected to the city walls. It is a historic gateway leading into the Old Town of Kraków. The barbican is one of the few remaining relics of the complex network of fortifications and defensive barriers that once encircled the royal city. It currently serves as a tourist attraction and venue for a variety of exhibitions.
The Gothic-style barbican, built around 1498, is one of only three such fortified outposts still surviving in Europe, and the best preserved. It is a moated cylindrical brick structure with an inner courtyard 24.4 meters in diameter, and seven turrets. Its 3-meter-thick walls hold 130 embrasures. The barbican was originally linked to the city walls by a covered passageway that led through St. Florian"s Gate and served as a checkpoint for all who entered the city.
On its eastern wall, a tablet commemorates the feat of a Kraków burgher, Marcin Oracewicz, who, during the Bar Confederation, defended the town against the Russians and shot their Colonel Panin. Masterpiece of medieval military engineering, with its circular fortress, was added to the city"s fortifications along the coronation route in the late 15th century.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
