No victims found in rubble of collapsed Wilhelminatoren in Valkenburg

Authorities have confirmed that no victims were found beneath the rubble of the Wilhelminatoren in Valkenburg, which suddenly collapsed Sunday morning. The confirmation comes after an extensive search involving drones, rescue dogs, and specialized teams from Germany.

Mayor Daan Prevoo stated that while no bodies were discovered, search teams did find clothing in the debris, which may have triggered the scent response of the rescue dogs. “The German team that conducted the deep search, also using camera footage, found only clothing,” Prevoo said. “The final conclusion is that there are no victims.”

The Wilhelminatoren, a historic observation tower on the Heunsberg, crumbled without warning. The cause of the collapse remains unknown. The tower’s observation platform had been closed for maintenance, but a brasserie located at the base was still in operation at the time of the incident.

Search and investigation

After the collapse, Urban Search and Rescue (USAR) deployed search dogs to comb through the debris. Two separate dogs independently signaled the same location, prompting emergency teams to carefully remove the rubble layer by layer. Specialists from the German Technisches Hilfswerk (THW) assisted in the operation.

In addition to the rescue efforts, authorities are investigating potential causes. Prevoo dismissed the possibility that underground movements from the nearby Wilhelminagroeven and Gemeentegrot contributed to the disaster. “Seismologically, there are no indications that movement in the caves beneath the hill caused the collapse,” he said.

The Royal Netherlands Meteorological Institute (KNMI) reported minor tremors in the region around 5:30 a.m. Sunday, detected by a seismometer near Valkenburg. However, the KNMI has stated that these readings make it unlikely that an earthquake was responsible for the collapse.

Officials are now reviewing the permit process for maintenance work on the tower. “We are investigating whether there are any indications in the permit that could provide clues about the cause of the collapse,” Prevoo said.

The collapse raises concerns about the structural stability of the area. A footpath leading to the tower, the Wilhelminatorenvoetpad, has been closed since the severe flooding that hit Valkenburg in July 2021. Heavy rainfall had partially washed away the path. Plans to reinforce it were scrapped due to concerns that the weight of added materials would put too much strain on the underground tunnel network. The same issue affected the Gebösjkevoetpad on the hill.

The unexpected destruction of the Wilhelminatoren has shocked residents and tourists alike. The tower, more than a century old, was an iconic part of the Valkenburg skyline.

“We cannot believe that you can now drive into Valkenburg and not see the Wilhelminatoren,” said Manon Luijten of Visit Zuid-Limburg. “It was a defining feature of the landscape, and its loss is enormous.”

The collapse has also impacted local tourism. While the Fluweelengrot and Kasteelruïne remain open, access to the Gemeentegrot is restricted. Visit Zuid-Limburg has pledged to support affected businesses, including Attractiepark Kabelbaan Valkenburg, which managed the site and operated attractions such as a toboggan run and a mini-golf course.
