Hospital Blockhouse Museum, Military heritage museum in Les Sables-d'Olonne, France.
The Hospital Blockhouse Museum is an underground medical facility in Les Sables-d'Olonne, originally built during World War II. The bunker contains around twenty rooms filled with medical equipment, instruments, and objects from the occupation period.
The facility was built in 1944 as a field hospital to treat the wounded and support the coastal defenses of the Atlantic Wall line. After the war, the bunker was partly filled in but later opened as a memorial site.
The museum displays how medical staff and patients lived and worked inside a bunker, with original instruments and personal items from that era. The exhibits offer a direct sense of daily life under extreme conditions underground.
The bunker is located near the city center and accessed by several staircases, which requires some physical effort when entering and exploring. The rooms are tight, so expect crowding, and wear comfortable shoes.
The bunker preserved a functioning power supply and ventilation system, still partially visible today, showing the challenges of underground work. These infrastructure elements are rare examples of the engineering of that period.
