The Neuengamme concentration camp was established in 1938 by the SS organisation. It was operated by the Nazis from 1938 to 1945. Over that period an estimated 106,000 prisoners were held at Neuegamme and at its subcamps. The camp served the needs of the German war machine and also carried out exterminations through labour. The inmates were spread over approximately 80 subcamps across northern Germany. At least 50,000 succumbed to the inhumane conditions in the camp from hard manual work with insufficient nutrition, extremely unhygienic conditions with widespread disease, and violence from the guards.
After Germany's defeat in 1945, the British Army used the site until 1948 as an internment camp. In 1948, the facility was transferred to the Hamburg prison authority which tore down the camp huts and built a new prison cell block. After being operated as two prisons by the Hamburg authorities from 1950 to 2004, and a period of uncertainty, the site now serves as a memorial.
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.
