Pieskowa Skała castle, built by King Casimir III the Great, is one of the best-known examples of a defensive Polish Renaissance architecture. It was erected in the first half of the 14th century as part of the chain of fortified castles called Orle Gniazda (Eagles Nests).
The castle was renovated and donated in 1377 by king Louis I of Hungary to Piotr Szafraniec of Łuczyce, according to a more modern interpretation by the 15th century chronicler Jan Długosz, but the family gained the full ownership rights of the castle only in 1422 from King Władysław II Jagiełło in recognition of the faithful service at the Battle of Grunwald by Piotr Szafraniec, the chamberlain of Kraków.
The castle was rebuilt in 1542–1544 by Niccolò Castiglione with participation from Gabriel Słoński of Kraków. The sponsor of the castle's reconstruction in the mannerist style was the Calvinist, Stanisław Szafraniec, voivode of Sandomierz. At that time the original medieval tower was transformed into a scenic double loggia decorated in the sgraffito technique. Between 1557 and 1578, the trapezoid shape courtyard was surrounded at the level of two upper storeys by arcades, embellished with 21 mascarons. The arcade risalit above the gate is a 17th-century addition.
The last owner of the castle of Szafraniec family was Jędrzej, Stanisław's son, who died childless in 1608. After his death the estate was purchased by Maciej Łubnicki and later by the Zebrzydowski family. In 1640 Michał Zebrzydowski built the bastion fortifications with baroque gate and a chapel. The castle changed hands many times over the centuries. In 1903 it was bought by the Pieskowa Skała Society led by Adolf Dygasiński and with time turned over to the Polish state and meticulously restored.
References:Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
