The AquaDom (mixed

Berlin-Mitte, Germany.[1] The DomAquarée complex also contains offices, a museum, a restaurant, and the Berlin Sea Life
Centre aquarium.

On 16 December 2022, the AquaDom aquarium ruptured, destroying itself and propelling the 1,500 fish inside into nearby facilities and streets, killing the majority of them and causing considerable damage. The former AquaDom will not be restored but will be replaced with an

indoor garden in 2024.[2]

Construction

The AquaDom was opened on 2 December 2003[3] at a cost of about 12.8 million euros.[4] The acrylic cylinder was manufactured by International Concept Management, Inc. using Reynolds Polymer Technology panels, with architecture drawings provided by Sergei Tchoban. It was located in the same building as the Berlin Sea Life attraction but was owned and operated by Union Investment.[5][6]

The aquarium was constructed from 41

Guinness World Record for being the world's largest cylindrical aquarium.[8]

scuba divers.[7] According to Union Investment, the owner of the building complex,[10] the wall thickness of the outer acrylic cylinder was 22 centimetres (8.7 in) at the bottom and 18 centimetres (7.1 in) at the top. The water temperature was kept at 26–27 °C (79–81 °F).[11]

In 2020, the aquarium was refurbished and upgraded, with all the water drained from the tank and the fish temporarily relocated to a breeding facility in the basement.[12] According to the owner, seals were renewed at the base and an additional sealing level was fitted. The cylinder was repaired and polished in places. Maintenance work on the elevator was carried out.[11]

Destruction

Rescue workers searching through the debris of the AquaDom on the morning of December 16, 2022.

The cylindrical tank burst at 5:43 am local time (4:43 am GMT) on 16 December 2022. Approximately 1 million litres (260,000 US gal; 220,000 imp gal) of water poured into the hotel and street, together with the 1,500 fish it hosted, devastating the interior of the hotel and eliciting a large-scale deployment of rescue workers.[13] Two people were injured and hospitalized, with officials and the media noting that the collapse would have likely resulted in several fatalities had it taken place later in the day.[13][14][12] The majority of the 1,500 fish were killed as a result.[15] Hundreds of smaller fish in the facility's breeding tanks were endangered as power was lost but they were successfully rescued.[15][16] The Technisches Hilfswerk (THW) rescue team completed their operation after 12 hours but the hotel's lobby and atrium remained devastated – "It looks like a battlefield".[16]

The rush of salt water damaged several nearby businesses, including a

seismographs.[13] Most of the seawater drained into the street's storm drains and sewers. The basement of the DDR Museum was also flooded and reopened three and a half months later.[17][18] Sandra Weeser, a member of the Bundestag who was staying at the hotel at the time, described being woken up by "a kind of shock wave".[19] There was no suspicion of foul play, with a spokesman for the owners of the tank stating the reason for the collapse was not yet clear.[13]

Failures and major leaks have occurred at several large acrylic aquaria before, those accidents including the T-Rex Café at Disney Springs in Orlando and the Dubai Aquarium at the Dubai Mall.[20][21] In advance of a safety investigation, material fatigue has been named as a possible cause,[22] and the large temperature difference (the night-time temperature in Berlin was −9 °C (16 °F), while that of the water was 26 °C (79 °F)) was identified as dangerous for the material.[23]

As of 24 October 2023, prosecutors closed the investigation into the rupture after an expert report failed to determine its cause conclusively.[24]

Future

In April 2024, it has been announced that AquaDom will not be rebuilt with its remains being converted and redeveloped into an

indoor garden by autumn 2024.[2]
