Beilinson Hospital in Petach Tikvah, Israel, one of Israel’s largest medical centers, has opened an underground, fortified hospital in anticipation of further escalation of the Israel-Hamas War.

The complex spans 53,819 square feet and two floors of the hospital’s underground parking garage and holds 200 patient beds, an intensive care ward, two patient wards, and a dialysis unit with 20 stations, according to a hospital press release.

It was initially built a few years ago for $8.9 million and has since been used four times during large-scale military operations and to host several Israel Defense Forces simulations and trainings.

The wards were re-located from the higher floors of the hospital’s patient towers and moved underground at the start of the war.

Additionally, all above-ground hospital buildings, including the Davidoff Center for cancer treatment, Gur Shasha Tower patient tower, and the Women’s Hospital, have secure spaces and floors to continue to treat patients without having to move the most critical ones during an attack, according to the release.

The hospital’s emergency department is located one floor underground and includes a trauma center and more than 100 stations to treat ambulatory and non-ambulatory patients.
