We were touring the UK and came across some memorial plaques in Falmouth harbor that had been donated by the people of France for a group of sailors and commandos who carried out a daring raid on some locks in the Nazi held port of...More

The submarine base is a huge reinforced concrete edifice, which seems to have survived pretty much by accident - it is only since the turn of the century that the town has started to develop the area for tourism. Bits of the base have now...More

The uboat pens are hard to miss as they somewhat dominate the town. Not all areas are accessible as some bays have been repurposed as a museum a venue and a gift shop. You can still get a sense of the scale and purpose of...More

This is somewhere I have wanted to visit for a long time as it is a well known base from WW2. The sheer scale is amazing and to know the pounding it took from allied bombs in WW2 and it still stands today. Quite a...More

Felt a bit disappointed with the pens, having visited many of the other major WW11 sites the construction of the pens is amazing but no U boat. The only submarine here is a French one from the 70's. I'm sure a lot more could be...More

This was quite the u-boat repair facility endeavor by the Germans. It's bay after bay of repair facilities--worth walking the whole length. That French resisters attempted to blow it up is commendable and of course, doomed because of its immensity. Brings history alive. Well worth...More

Very interesting and thought provoking not just the buildings but the history of the place. And it's free!

I think this is the only place where you can see something so special as a WW II submarine base. It is really impressive. Go around, walk on top of it (there is an elevator) and then visit also the submarine L'Espadon which is opposite...More

This massive structure is accessible up a long open walkway. Luckily there is also a lift from the side of the pens. The sheer massiveness of the place is awe inspiring. Ceilings 5 meters thick. Just reading about it over a cup of coffee makes...More
