According to reports 21 male asylum seekers are currently staying at the site, where thousands of slave laborers were imprisoned and killed during the Nazi era.
The labor buildings of the camp where the inmates were forced to work have since been demolished, and the current occupants, some of whom have been staying there for months, are housed in the site's former barracks.
The use of concentration camp is one of the answers to the pressing problem for the German authorities on where to house the quota of 800,000 asylum seekers Germany has agreed to take this year.
At the end of August the authorities in Berlin announced they were making plans to use the city's closed Tempelhof airport, which spans more than 300,000 square meters, to provide accommodation for some of those seeking refuge.
"It is an emergency solution, but it is unavoidable. There is a lot of room in the hangars," the Mayor of Berlin's Mitte district, Christian Hanke, explained the decision to use the airport, which was built in the 1920s, but is now an abandoned listed building.
*CORRECTION: After the publication of the article, it emerged that some details were inaccurate. The refugees have been housed on the site of former Nazi labor camp Schwerte-Ost, which was a sub-camp of Buchenwald, not on the site of Buchenwald itself. The headline and the summary of the article have been changed accordingly.
