As of today, seven systems of shelters and tunnels belonging to the “Komplex Riese” are known to exist in the Owl Mountains. The exact purpose of these facilities remains unclear even today. They are all of a similar design, corresponding to the layout of other of Adolf Hitler's subterranean headquarters.

The rumours surrounding the intention of these unfinished caves may well be one of those things to which we will never know the answer but visiting the complex enables you to understand the vastness of the project and the dangers the workers would have gone through.

Jawornik, Soboń, Gontowa, Książ, Rzeczka, Włodarz and Osówka belong to the underground project called RIESE (= "giant" in German). The last three are accessible for tourists, Książ as well but only in a small part. Until now we don't have a clear proof as to what was supposed to be created here, but there are 2 hypotheses (underground weapons factory... More

One of the biggest constructions conducted by Nazi Germany during WW2 as a part of secret project codename Riese. Very misterious place with different theories surrounding it. Important notes: - Think about this place more like huge abandoned mine or construction site can be demending for older people. -Note that it's one of 3 underground facilities open to the public...

After reading reviews from TA, I found it quite challenging to visit the place. Fortunately, I discovered the Vratislava private tour which can take us to this place. The Project Riese at Osowka is almost a two hours drive from Wroclaw. After arriving, without following the other locals in a polish tour our driver/guide Michal took us inside with English... More

My partner and I rented a car because we wanted to visit Project Riese. It's 85 km from Wroclaw but quite a drive through the midlands. We reached Osowka in 100 minutes. The tour goes almost each hour in the summer, but is also only in Polish. An English or German audioguide is available but costs 16 zl (€3,50). Our... More

This was a very unique experience. The tunnels are part of Hitler's Riese Project and is located in Osowka, Poland near Wroclaw. We were with a Polish speaking group, but an English speaking guide tried to translate everything for us. There are remains of tanks and machine guns. Hitler's men used the tunnels to build airplane parts. The tunnels are... More

As others on this site have mentioned this site is quite a drive from Wroclaw. It is a unique historical sight and worth the effort. On the day we visited the guide spoke little or no English, but the tour of about 1 hour was explained by an audio guide in English (separate charge). The only problem with it was... More

The story of Projekt Riese is chilling and fascinating, and we understood that Osowka was the most worthwhile to visit. It's run as a privately-owned tourist attraction, and as we hadn't taken the precaution of booking an English (or German) language tour (extra charge payable) we tagged along with a small Polish-speaking group. Even allowing for our incomprehension, the guide's... More
