it is located 18 km north of Gierłoż, on a side road from Kętrzyn to Węgorzewo. The quarters were built in the fall of 1940. It was constantly modernized and expanded until the fall of 1944.
The complex consisted of over 150 buildings, including 29 reinforced concrete air-raid shelters and covering technical infrastructure.
The area was divided into three zones:
In Zone I "Quelle" there were shelters and OKH buildings.
In Zone II "Fritz" there were bunkers and buildings of the Land Forces Quartermaster and a railway station.
In Zone III "Brigitte Stadt" there were shelters and buildings for communication and auxiliary services.
Bunkers V2 (2 internal rooms) and K5 (5 internal rooms), built in the first period of construction, had external walls and ceilings 2m thick.
After increasing the air risk to the headquarters, in the spring of 1944, the strengthening of the building began. The existing shelters started to be covered with a layer of reinforced concrete with a total thickness of 4-6 m (shelters after reconstruction VO2 and KO5).

Mamerki - Zone I Quelle
Highlight • Historical Site
The bunker museum in Mamerki (Mauerwald) houses one of the best-preserved German headquarters from World War II, whose huge concrete colossi survived the war completely unscathed. Exploring the gloomy bunker facilities and reconstructed exhibitions – such as a replica of the legendary Amber Room – you will delve deep into the oppressive history of this protected forest area.

Upper Leśniewo Lock
Highlight • Monument
The lock in Leśniewo is one of as many as 10 locks that were to be built on the Masurian Canal, a huge undertaking of the Prussian state at the time. In total, there were to be 5 of them in the territory of today's Poland, and the lock in Leśniewo was the first on the canal from the side of Lake Mamry.
The size of the lock itself is truly impressive - 46 meters long, 7.5 meters wide and with a 17-meter drop. To this day, a clearly visible groove for the Nazi eagle can be seen on the front wall of the lock. This is a rare case of preserving such a hated symbol in Poland. It survived only because it is only a niche for the emblem of the Third Reich.
Today, however, the monumental and mysterious lock in Leśniewo Górne is treated mainly as a monument associated with the Masurian Canal. And as a result, it has also become one of the fascinating attractions of Masuria and the area around Lake Mamry. The extreme rope park that operates here in the summer attracts many adrenaline-hungry daredevils every year. plannawypad.pl/sluza-w-lesniewie

Leśniewo Górne Lock (Masurian Canal)
Highlight • Monument
Monumental, gloomy, mysterious but also fascinating. The remainder of the domination of the Third Reich in Europe is also a symbol of the mystery that accompanies the Masurian Canal. Therefore, while in this region of Masuria, it is worth seeing the dam on this object. The huge, concrete building with traces of the symbolism of the Third Reich still inspires terror and an atmosphere of mystery that accompanies the conjecture about the actual plan for the expansion of the Masurian Canal. Were there supposed to be submarines built in the area, which could reach the Baltic Sea through the Masurian Canal? Or maybe the Germans planned a completely different investment, and why was such a monumental structure built as this dam?
The lock in Leśniewo Górny is 46 meters long, 7.5 meters wide and has a 17-meter drop. It was completed in about 30% (70% according to other data). On the front wall of the lock, you can see a recess in which the symbol of the German eagle was to be placed. Currently, there is a rope park in the lock area. Thanks to this, you can reach the top of this facility via a special pier and see its monumental form, or take advantage of more extreme adventures, using rope descents. It is also a form of visiting this object. The use of the rope park will surely leave you with an unforgettable experience.
The lock is an element of the mysterious Masurian Canal. To this day, it is not known what specific goal the Germans set for this facility. The project to build the Masurian Canal appeared at the end of the 19th century - as a route connecting Masurian lakes with the Baltic Sea. The idea was to quickly float the timber towards the Baltic ports and to develop tourism. The use of water to create electricity was also considered. During the war conflicts, the channel gained a different, more military significance.
One of the latest technical projects indicates that ten steps are planned to be built with slopes ranging from 5 to 17 meters. The construction of the canal started in 1911. However, the works were stopped when World War I broke out. The idea of building this facility was returned in 1934. Then the canal became a secret project. However, the implementation of this plan was interrupted again in 1942.
