Maybe you didn't know, but in Jersey was a heavily fortified island with coastal fortifications during Nazi Germany's occupation of the Channel Islands. They were amongst the most heavily fortified parts of the Atlantic Wall.  In Jersey, the fortifications included Hohlgangsanlage tunnels and artillery batteries such as Battery Moltke and Battery Lothringen.

The most distinctive new structures the Germans built were the Marine Peilstand (MP) towers that they used to search for targets at sea. The Germans had intended to build nine towers, but only completed three. These towers are round and have five or more floors with observation embrasures, as well as defensive embrasures. MP1 is part of Battery Lothringen, MP2 overlooks Corbière lighthouse and is now known as the Radio Tower, and MP3 is part of Battery Moltke. 

In 1946, after the British Army dismantled the World War Two German gun batteries in Jersey, 29 guns were thrown from off the cliffs at Les Landes: 

• Batterie Haesler, 4 x 15cm K18 field guns.
• Batterie Schiefflen, 4 x 15cm K18 field guns.
• Batterie Mackensen, 3 x 21cm Morser 18 howitzers.
• Batterie Lothringen, 4 x 15cm Skl/45 Ship guns.
• Batterie Roon, 4 x 22cm K532 (f) field guns.
• Batterie Moltke, 4 x 15.5cm K 418 (f) field guns.
• Batterie Ludendorff, 3 x 21cm Morser 18 howitzers.
• Batterie Hindenburg, 3 x 21cm Morser 18 howitzers.

Many of the guns can still be seen today. 7 of the guns have been brought back up for display across the channel islands, like the original 15.5cm K418(f) French field guns from the battery 'Moltke', retrieved in the 1990s.
