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.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
