I visited the underground hospital with my teenage son who is about to join the RAF. He found it fascinating. This is my second visit to the site, my original visit being over 20 years ago. In that time the site has been upgraded and I really enjoyed my revisit. I would recommend visiting it and it’s especially comfortable on a hot day as the tunnels provide cool and pleasant surroundings !

Well worth a visit much larger than expected its pretty chilly in there so taking a jacket is a good idea. Martin was so helpful we left at closing time and had missed the bus! Martin very kindly offered us a lift back to our hotel thanks so much ⭐️⭐️⭐️⭐️⭐️

This is a fascinating yet haunting place. A labyrinth of passages thankfully well signposted takes you deep underground to experience the lengths went to by the Germans to build the place. Only in use for three months it took three years to build by forced labour. Details of some individuals who were enslaved there can be read as well as information about how it was built and what is was ultimately used for. Very well lit and overall well presented preserving this piece of history which is so important.

Adds an additional picture /story to this time, to the one of Jersey War Tunnels, in Jersey. This one has less exhibition information, and is very crude, naked, cold, and creepy. Damp, very cold (yes, do put on a cardigan and a jacket, even in the summer). Very small 'shop', and no cafe / lunchrestaurant (compare Jersey War Tunnels). Still worth while visit. Adds to the more full picture of a gruesome time, and the hardships to the peoples in the Channel Islands.

Informative guide at entrance. Not expensive. Car parking just opposite. Impressive excavations but I did not find much inside. Lots of condensation inside making floors a bit wet etc.

This is an incredible structure and so large with so many corridors. It was so hard to comprehend how it was made . It apparently took 3 1/2 years to excavate. It was only used for 9 months. You are given a map and there are very good signs to guide you around and there are signs to help you find your way around. The corridors are lined in Concrete sections and some are lined with bricks. It must have been very oppressive. There are some interesting information board that tell you about some of the Guernsey people of the time. There are displays of items to see and some hospital wards with beds. The beds where very close together. There were some escape ladders that would have been quite frightening to use. If you visit wear warm clothing as it is quite chilly when you walk around. Suitable shoes for damp and wet floors are useful. It is certainly an impressive structure that must have been terrifying for those involved in its creation. Good place to visit on a wet day.
