Olavsvern
You will find the decommissioned Royal Norwegian navy base outside Tromsø, Norway. The huge mountain complex has a submarine hanger built with direct sea access. The government decided to shut it down in 2008 after restructuring the navy. It was even placed on the market in 2011. It went to an oil rig firm for 38 million kroner or $4.3 million! Rumors say Russian military activity is going on there.

The Maginot Line, France
In the ‘30s, the French Government built the Maginot Line, which ran along the German border. It was meant to stall German invasion and allow them to mobilize their army in the meantime. This was a great idea on paper, but it was not very effective. The Germans simply invaded from another direction and conquered the country in only six weeks back in 1941. It was also too costly to maintain, especially during wartime. It still exists, although it has not been maintained or used in a long time.
