Sloup Castle is a rock castle in the municipality of Sloup v Čechách. It takes its name from the special appearance of the freestanding 35-metre high sandstone rocks (its name literally means 'column'), into which it was carved in the 14th century.
The castle was first mentioned in records dating from 1324 owned by Čeněk of Ojvína. It was established beside a salt trade route from Meissen to Česká Lípa by the Ronovec family. The edges of the outcrop, which was a level summit, were carved to resemble castle walls with loopholes, and some of the gullies in the outcrop were filled in with masonry. Thanks to an ingenious system of trenches it was possible to flood the area around the rocks. The combination of natural conditions and human ingenuity turned the castle into a fortress unassailable by medieval warriors.
During the 15th century, Knight Mikeš Pancíř of Smojno was based here and launched a raid on Lužice, and as a consequence the castle was besieged in 1445–45. When the starving troops capitulated after three months of isolation it was burned down by the end of 1447. The castle was repaired, but it gradually ceased to meet the desired standards of comfort, and during the 16th century it was deserted and became dilapidated.
In 1639, the Swedes burned it down, and the castle became a ruin. From 1670 to 1785 hermits were based here, making use of the rock for their needs. Among other things, they carved out new rooms and created recesses for the Stations of the Cross, built a chapel in the rock and formed a new entrance. Historical documents talk about several men: Konstantin was a bricklayer; Vaclav painted a solar clock on the wall; and an optician and gardener called Samuel grew corn on the plains around the castle, as well as wine on its southern terraces.
After the hermitage ceased to exist the state owners, the Kinsky family, turned the complex into a romantic tourist attraction. Little has been preserved of the original structure on the elevated plateau, although the spaces sunk into the rock can be clearly seen today like the dungeon, well, hermitage, passage and the terraced walkways. In the former prison, dungeon carvings have been preserved, which were dug out of the walls by former prisoners. Sloup has now become a romantic place for outings and occasionally candlelit concerts and historical jousting matches are held.
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.
