A giant aquarium containing a million litres of water in the lobby of the Radisson Blu in Berlin has burst, flooding the hotel and nearby streets.

The “AquaDom,” which was 14 metres (46 feet) high and contained 1,500 tropical fish, has been dubbed the largest free-standing cylindrical aquarium in the world.

According to Reuters, two people were injured by the glass.


Police said there had been “incredible” damage. The video showed an empty tank, water pouring into the lobby, and debris strewn everywhere.

Guests have been moved out of the hotel following the incident at 05:50 (04:50 GMT).

The front doors of the Radisson Blu are now hanging into the street, distorted at an angle by the pressure of the exploding tank, and a pile of rubble is in front of them.

The hotel’s damage was inspected by Berlin’s mayor, Franziska Giffey, who compared the tank explosion to a tsunami.

She expressed relief that it had occurred so early in the day, noting that if it had occurred an hour or so later, the lobby and the street outside would have been crowded with guests, many of whom would have been children.

Since the aquarium was updated two years ago, visitors can use a clear-walled lift inside. The hotel advertises that some of its rooms have views of it.

More than 100 firefighters were present, according to Berlin’s fire department, while the cause of the accident is still unknown.

The hotel’s interior was allegedly searched by rescue dogs to find any potential victims, but none were found.

Police warned locals to drive carefully as “massive amounts” of water was gushing into the streets nearby.

According to a police source who spoke to the local media, there is no proof that the break was caused by a targeted attack.

There were more than 100 distinct fish species in the aquarium.

On Friday, the attraction posted a notice on its website asking guests to reschedule their tickets due to a temporary closure of the attraction.

The largest cylindrical aquarium in the world, AquaDom received the Guinness World Record after it debuted in December 2003.

Its construction reportedly cost about €12.8 million (£11.2 million) at the time.
