(CNN) — A luxury hotel, complete with a lush rooftop garden, is set to open within a huge former Nazi bunker.
Originally called Flakturm IV (Flak Tower IV), the Hochbunker in the St Pauli district of Hamburg is testament to Germany’s wartime past.
Built in 1942 in just 300 days, the bunker in the St Pauli district has been in constant use since the Nazis were defeated three years later, bringing an end to World War II.
Civilians were initially accommodated in the building during Germany’s postwar housing crisis. The space was later used by a German TV station and other businesses.
Now a hotel is set to be established there too, with the whole complex set to undergo a massive overhaul that includes an innovative landscaping project.
The rooftop park, which will be open to all the inhabitants of the building, will include a memorial center for the victims of Nazi Germany.
The plan is to extend it by five pyramid-like floors, with the lavish roof garden offering a panoramic view over the city. According to planners, it will feature a “planted ‘mountain path’, which winds upwards around the bunker.”
More than 1,000 bunkers were built in Hamburg during the war and the Hochbunker was one of the largest in Germany. According to the official Hamburg site, in 1942 some 1,000 forced laborers were ordered to build the structure — measuring 75 by 75 meters (246 by 246 feet) wide and 35 meters (115 feet) high, including walls that were 3.5 meters (11.5 feet) thick.

Designed to accommodate 18,000 people, it had a wide entrance to accommodate women pushing baby carriages. Some 25,000 people sought shelter there during the summer air raids of 1943.
Plans to demolish it after the war were dismissed, according to the Hamburg website, as the amount of explosives required would have been likely to tear down surviving residential areas too.
Schulze told CNN the hotel chain is not running the building scheme, but is a tenant like the other 40 companies which “continue to have their home in the bunker.”
“In addition to this new public natural oasis, the bunker will for the first time receive a memorial to the victims of the Nazi regime and the Second World War,” he added.
Maarten Markus, managing director Northern Europe, for the NH Hotel Group said in a statement to CNN that his company was aware of the history and significance of the building.
“Our design and lifestyle brand has an inclusive approach, meaning that nhow Hamburg will integrate itself into the neighborhood and creative scene.”
The public roof garden will be freely accessible, say planners.

The concept is likely to tap in to the growing trend for dark tourism, which involves travel to sites where death or suffering has occurred or been memorialized. Locations can include Holocaust sites, battlefields, prisons, slavery sites, graveyards and other places of great suffering.
“Plans for an in-house memorial within the hotel shows how sensitive heritage can be appropriated, and where heritage can help us remember, whilst in some places history is forgotten.
“Future guests may be drawn to the hotel because of its difficult heritage, and there will always be a fine ethical line between exploitation and commercialism. The task is to appropriate the building in a responsible way and to provide guests with an authentic narrative. In that way, dark tourism can shine a light on our painful past.”
