Saint-Nazaire

The massive hulk of the Saint-Nazaire submarine base. Inside are several museums, and across the basin is the submarine Espadon

For the story behind this base and this tour, check out Silent steel and a concrete castle.

Pens

There are 14 pens total. Some are regular docks, some are dry (docks).

Roof

The roof is 26 feet (8 meters) tall with four layers of reinforced concrete, granite, more concrete, and steel. They wanted it impenetrable to aircraft, and given the shape it's still in, after 13 aerial bombing attacks and 70-plus years that goal seems to have been achieved.

Ville-Port

For decades, the pens and the area around it were either vacant, or just for industrial use. Now the area is well developed, renamed Ville-Port, and there's a cafe, a night club, the museums, and across the street, a mall with restaurants and shops.

Interior walls

Well, something has to support that massive ceiling and its huge reinforced concrete walls that divide the different pens.

What the...

After making my way through a dark and narrow passage between two pens, I exited to this in shock. A massive cruise liner! It took me a moment to realize it was a trick of lighting and mirrors, and was just a small segment. Inside is a separate exhibition called Escal'Atlantic about the many incredible ships of this type built in Saint-Nazaire.

Roof

Now essentially a public park, with ramp access to the shops across the street, the roof of the base would have been covered in anti-aircraft batteries during the war.

Diagonals

Being in the shadows for a bit was a welcome respite from the sun. Many of the "roof-above-the-roof" slabs were added later in the war to help protect from ever-more-powerful Allied bombs.

Originally the Espadon had two rear torpedo tubes. These were removed in the mid-'60s and replaced with a chamber for combat divers to enter and exit the sub while underwater.

New diesels

Not surprisingly, those engines got replaced only a few years after launch. Three new SEMT Pielstick 12 PA4-185 V12 diesels were installed, each producing around 952 hp each. They'd need to run every 5 days for roughly 5 hours to keep the batteries charged.

Ops

The layout on the Espadon is a bit different from most subs I've toured. There's less of a feeling of "this is ops" as much as it's "here's a bunch of equipment with benches in a hallway."

Into the sail

Very few submarines that you can tour have ladders, especially in the middle of the sub. (Health and safety concerns.) But while in the Espadon's ops you can climb up a few rungs to have a look in the sail. The big tube houses one of two periscopes.

The Greatest Raid of All

The port of Saint-Nazaire was the location of what's called The Greatest Raid of All, a daring and flat-out incredible attack by the British on the only drydock outside of Germany large enough to repair the Tirpitz and Bismark battleships. The entrance to the Normandie dock, as it's called, is on the left here (it was filled with water during my visit, so not much to photograph). The mid and rear of the the destroyer HMS Campbeltown would have been visible in the center of the frame had this photo been taken that next morning. On the far right is Old Mole jetty, the planned escape route. 

Jeremy Clarkson, of Top Gear and Grand Tour fame, made an excellent BBC documentary about it. Definitely worth watching.

Art

From the roof of the fortified lock, you can see the art installation called Suite de Triangles, by Felice Varini. This is the only location where they all line up in a row like this. Some triangles, on the other side of the port, look heavily distorted from any other viewpoint. The top of one triangle could be on a completely different building. You can get an idea what it looks like in the Google Maps overview or this short video.

Sous marin Espadon

If you're fascinated by WWII history, a tour of western France is a must. The sub pens here for sure, with the Espadon as an added bonus, but of course the beaches of Normandy, with the Redoutable as an added bonus. 

The tour of the sub is 10 euros ($11USD/£8.50/AU$15.50), but there are other tours in the area, including Airbus, the shipyards and more, but most require booking well ahead of time.

Check out French naval and art meet in silent steel and a concrete castle for the more about the base and this amazing submarine.
