10 Of The Most Impressive Underground Places I’ve Visited In Europe

Hello! I am an urban explorer from Lithuania. Since 2011, I have been exploring abandoned places in Lithuania and Europe. I have traveled to nearly all European countries, trying to do at least several big trips a year. In each of these locations, I search for abandoned sites and other inaccessible places to the general public.

One of my favorite topics when traveling is exploring underground locations, such as military fortifications, bunkers, city sewers, drainage systems, mines, and underground quarries, which I have extensively explored across Europe. These places allow me to experiment with lighting and capture unique photographs. Today, I am excited to present 30 of my favorite underground locations in Europe. If you enjoy my work, feel free to follow me on Instagram.

10 PHOTOS

#1 Abandoned Underground Submarine Base In Albania

This 650-meter-long submarine base was carved into the rock in 1969. Each end had an entrance, protected by massive armored gates. Designed to accommodate eight submarines, the base is now completely abandoned.

#2 Disused Water Reservoir In Lithuania

Built in the early 20th century, this spectacular reservoir is vaulted by a dome and supported by columns. It is the most beautiful underground reservoir I have ever seen.

#3 Disused Subway Tunnel In Kyiv

There is a disused tunnel in the Kyiv metro, abandoned after the construction of the third metro line. It is very difficult to access, as it can only be reached through a functioning subway line.

#4 An Unfinished Command Bunker In Kyiv

This unfinished command bunker in central Kyiv is one of the most impressive underground sites I have ever seen. Three underground floors were planned, but only a massive tunnel with a ten-meter diameter, connecting to the Kyiv metro, was completed.

#5 Vilnius Underground

Vilnius, like most other old European cities, has its underground areas where you can take stunning photographs.

#6 Fairytale Tunnel In Odesa

This tunnel was used by vacationers to reach the sea from the sanatorium above. It is heavily decorated with motifs from Ukrainian fairy tales, making it one of the most photogenic places in underground Odesa.

#7 Quarries Around Paris

There are many abandoned limestone quarries near Paris. Occasionally, you can find underground lakes in them, but mostly, you will see large and tall columns that somewhat resemble the Mines of Moria from The Lord of the Rings.

#8 Mines In Slovakia

Slovakia is known among urban explorers for its abandoned mines of coal, metals, and even uranium. Often, these shafts are well hidden from prying eyes and can be difficult to find.

#9 Regenwurmlager

Often referred to by urban explorers as the largest underground military structure in the world, this Nazi fortification was designed to protect Germany from an eastern attack. Between 1928 and 1938, 34 bunkers were constructed, connected by a 30-kilometer underground railway. We spent three days exploring this system, sleeping and eating underground while carrying all our supplies in backpacks.

#10 Abandoned Train Tunnels In Europe

There are many abandoned train tunnels across Europe, including in Belgium, France, Ukraine, and even Lithuania. They often provide opportunities for spectacular photos.
