Rummu Underwater Prison Survival Guide | Tallinn Estonia

Most tourists visit Estonia during a one-day stop on a cruise ship holiday. Those that have the luxury to explore deeper can seek out a day of adventure that even James Bond would find alluring. The cities of Rummu and Ämari offer travelers the chance to feel like a secret agent in some off the beaten path experiences. Come see what’s behind the barbed wire, DO NOT ENTER signs, concrete walls at the Rummu Underwater Prison.

Rummu Underwater Prison

Not in their wildest imaginations did the prisoners that once worked this quarry ever consider that their daily hell would one day turn into a summer hotspot.

Just outside the small town of Rummu, lies the ruins of the old Soviet Prison with a very dark past. In the 1940s, this limestone quarry served as an active labor camp. The prisoners were forced to toil the land as the guards watched on from the buildings and towers. During that time, the underground springs seeped water that needed to be continuously pumped to keep the quarry-bed dry.

In the 1940s, this limestone quarry served as a Soviet labor camp.

When Estonia regained its independence in 1991, many of the Soviet institutions were vacated, including the Rummu Prison. With no one to clear the accumulating water, a lake quickly formed, swallowing much of the machinery, concrete barriers, and buildings located near the spring.

Today the remaining buildings are dilapidated and graffiti-laced. However, the site is truly mesmerizing with the dramatic limestone dunes and clear, turquoise water. Some of the beachfront buildings even feature some cheerful artwork, helping to calm your nerves if you’re exploring this eerie place all alone.

The Rummu Underwater Prison is a prime diving location due to the great visibility of the natural groundwater. Divers enjoy exploring the sunken ruins and watching for wildlife, like frogs and fish. In the summer, locals turn it into an adventurous beach destination.

Rummu Prison Travel Tips

As you arrive at the entrance, you will see the gates covered with barb wire and DO NOT ENTER signs. It can be quite intimidating. However, seeing the Rummu Prison listed on TripAdvisor encouraged us to go in. There are photos of sunbathers, repellers, and crazy teenagers jumping into the lake from the ruins.

Ämari Air Base and Soviet Cemetery

The graves of many of the military pilots are topped with actual tail fins from the Russian aircraft that they flew.

While touring this part of Estonia, we witnessed a lot of military activity. There were tanks on the road, helicopters circling overhead, and fighter jets whizzing by. We learned that Ämari Air Base is located near the Underwater Prison. This is an active NATO base that carries out Baltic Air Policing patrols.

Nearby, there’s an interesting travel oddity that can be found tucked away in the forest. An old historic cemetery holds the remains of a number of pilots who flew under the Estonia Soviet regime. What makes this place unlike any other historic cemetery are the unique grave markers. The plots of the Soviet military pilots are topped with the actual fins from their very own Russian aircraft. It’s an eye-catching sight from the road and definitely worth a quick stop for a look.
