Guernsey is full of recent history and the island was the closest place to mainland Britain to be occupied by the Germans during World War 2. Occupied by Germany during World War 2 there are many concrete bunkers and deep tunnels holding Guernsey’s history. The German underground military hospital holds an eeriness to it however I would say these are definitely worth a visit even if history isn’t your thing!

Liberation Day is an annual holiday in Guernsey held on the 9th May. This is the day that Guernsey was liberated from the Germans. Huge celebrations take place over the island. The roads in St Peter Port close and the parades take place throughout the day with gunshots from the famous Castle Cornet. This is a bank holiday on the island and everyone who has the day off heads out to celebrate.

German Underground Hospital and Bunker

The German Underground Hospital and Bunker is the largest WWII structure in the Channel Islands at 75,000 feet. The maze of tunnels below ground level would be completely unknown except the large concrete entrance.

It wasn’t until 1944 that the decision and transformation were made to turn the tunnels into the Underground Hospital.

The Underground Military Museum is a great place to learn about Guernsey’s military history including both World War I and the German Occupation during World War II.

The German forces used this underground tunnel for storage of their U-boats and fuel.

Today the museum stores a mass amount of history, including memorabilia and exhibitions from the German occupation. The Underground Military Museum is walkable from the town terminus bus station.

The castle was originally situated on a small island off of Guernsey’s mainland, which was only accessible by foot at low tide.

As the island grew in population and the harbour of St Peter Port expanded out to sea, access to the castle was eventually granted by bridges and harbour walls.

What is the Best Travel Insurance?

I know travel insurance is the least enjoyable thing to purchase and look at when you’re planning a trip, however, you wouldn’t want to be without it in the event that something happened. Accidents can happen anywhere and the extortionate medical bills will ruin your trip if you are not covered.

To ensure you have a stress-free trip with no worries about potential medical bills, make sure you cover yourself when you travel. We can recommend using Safetywing, a backpacker-friendly and cheap insurance company that provides good coverage and support.
