The bunker was in the Herz-Jesu-Viertel at Ottostraße 23 and the corner to Lambertistraße. The area surrounding the former bunker building consists of closed residential buildings, opposite the former bunker location there is a small park. The land on which the bunker stood has a size of 1227 m² according to the land register of the Münster District Court , sheet 3269. It is not within the scope of a development plan . On the back of the bunker facing away from the street, there was an open space on the bunker's property, which was shared free of charge by a neighboring property.

The bunker consisted of two parts of the building. The four-story protective bunker was alongside Lambertistrasse. The three-storey extension on Ottostraße formed the main entrance to the building. The roof of this part of the building was used as a roof terrace by a neighboring property in accordance with a usage agreement . The bunker had a cellar in part. It comprised 1501.59 m² of usable space, which extended over four floors.

According to estimates, the gross volume of the building with an interior height of 2.35 m was around 10,000 m³.

The outer walls of the bunker were 200 cm thick, the inner wall thickness was up to 60 cm and the top ceiling was 140 cm thick.

According to the plans, the bunker offered 1,160 shelter places. In the bunker, 1,100 people could survive independently for up to twelve hours .

history

According to the Münster city archives, the bunker was built in 1943 and 1944, but the years 1941/42 were immortalized in the fresh plaster in the bunker itself, although the authenticity of the latter is not guaranteed. In the years 1948 to 1950, refugees and displaced persons who were housed in the shelters created dated wall paintings showing landscapes and East Prussian coats of arms, which were deliberately not painted over during subsequent renovation work. The wall paintings included images of the coats of arms of Sudetenland , Breslau , Lower Silesia , Upper Silesia , Danzig , Stettin , Brandenburg , East Prussia , Königsberg , Pomerania , Ordensland , Posen-West Prussia and Posen . There was also a picture that was based on the painting Spring Dance by Otto Quante and with the inscription “Peace with dignity, whoever achieves this has climbed the pinnacle of life; Since everyday life is silent, eternal Sunday has come ” for him. Former prisoners of war and later also homeless men were offered the shelters as accommodation.

In the mid-1980s, the bunker was again prepared for civil defense and has since been maintained by the Münster fire department . During the Cold War , the city of Münster purchased almost 1,000 stretchers and cloth seats for the bunker. Since the end of the Cold War, the bunker has not been used as part of the federal civil protection program . The city's building regulations office used the second floor of the bunker to store files, which is why the bunker's ventilation system was activated for 15 minutes a day to keep the humidity at a constant low level so that the stored documents were not damaged.

A bidding process was ongoing until the end of October 2010, in which the owner of the bunker, the Federal Agency for Real Estate Tasks , tried to find a buyer for the property and the building. A purchase price of 350,000 euros was to be achieved, as set by the Federal Agency for Real Estate Tasks as the minimum purchase price . This amount was exceeded in the final sale and flowed into the federal budget , but its amount was unknown to the public. In January 2011, the Federal Agency for Real Estate Tasks awarded the highest bidder, a residential construction company from Münster-Roxel , the contract for the bunker, which is not under monument protection . In the same month the plans to blow up the bunker in October 2011 were announced, for which the city of Münster had given the demolition permit . It was planned to blast the two-meter-thick outer walls with so-called "low-vibration loosening blasts" to a thickness of 60 centimeters from the inside, in order to then remove the remaining building fabric with conventional means. Several thousand mini blasts, each with a few kilograms of gelatinous ammonium nitrate explosives , were planned for this purpose. This method was first used in 2010 when the Aalhof bunker in Lübeck was demolished . A working period of around four months was expected. According to experts, the cost of the demolition was higher than the purchase price. For future use, at the time of the sale and the demolition of the bunker, only “residential area compatible” concepts were permitted, including storage, culture, services, gastronomy and living. According to these specifications, three houses with 17 condominiums were to be built on the bunker's property, construction of which was scheduled to start at the end of January 2012 and whose completion was expected in spring 2013. These buildings should be ready for occupancy in summer 2013. The apartments should consist of two to five rooms, be suitable for senior citizens and have a living space of 75 to 150 square meters each. The residential construction project cost a total of 6.8 million euros and, contrary to the original plans, did without the establishment of shops on the ground floor. An underground car park with 17 parking spaces was created below the building complex. The topping-out ceremony was planned for January 2013. The plan was for the new buildings to be ready for occupancy by autumn 2013.

Hole in the Outside Wall (2012)

Two to five explosions have been carried out every day since October 2011. After the demolition work was delayed until the beginning of January 2012 and had to be extended until March 2012, there was an explosion on January 5, 2012, which led to glass breakage and property damage to the adjacent buildings on Lambertistraße. From the outer wall of the bunker, a boulder measuring two by two meters was blown up, which was only kept from falling onto the streets by a few reinforcement bars and after the blast it hung on the outer wall of the bunker. The cause is the lack of the assumed, continuous steel struts as well as an expansion joint filled with roofing felt, which did not provide sufficient resistance during the detonation, so that more than the desired first 120 cm detached from the 200 cm thick outer wall and led to the hole in the facade. On January 12, 2012, the blasting was continued on the walls facing the rear of the bunker under the condition that only 100 cm deep drill holes were used for the explosives.

According to the demolition company Moß from Lingen , the demolition work should be completed by Easter 2012 . This had been delayed several times after an incident occurred during the blasting work in January 2012 due to incorrectly estimated wall thickness. The increased chiselling work that followed led to increased noise pollution, which is why the period of time in which the work was noisy was gradually reduced.

At the beginning of April 2012 there was again property damage to the bunker adjacent to the bunker. Due to the vibrations of the demolition work, which was carried out using an excavator with a rock chisel attached, the bathroom ceiling of a resident collapsed. The floors of this apartment also sagged.

After the end of the demolition work, which was announced for Easter 2012, blasting was planned again to dismantle the massive floor slab of the bunker.

The demolition of the bunker was delayed by four months, which is why the sewerage construction originally planned in the residential area had to be postponed.
