Relaxation at the best price!
Between two waters
Hangar 3500 — the heart of the former factory
The most distinctive feature of the property is Hangar 3500. Its scale, industrial character and history make it one of the most unconventional event spaces on the Polish coast. It is a place where you can sense the building’s former purpose, while also seeing how history can become the backdrop for modern events. Hangar 3500 is more than just a hall. It is a living space — museum, conference, concert, recreational and family-oriented. For some, it will be the stage for a major event; for others, a place for a guided walk; and for hotel guests, a part of their stay that cannot be compared with any standard holiday resort.A hotel between the sea and the lake
The uniqueness of Arche Mielno also stems from its location. The Baltic Sea lies on one side, and Lake Jamno on the other. Between them are history, architecture and a space that allows guests to relax in a quieter part of Mielno. It is a location for those who want to be close to the sea but are looking for more than a classic seaside holiday. The hotel offers comfortable rooms and apartments, a restaurant, recreational spaces, a wellness area, attractions for families, the Warsztat 1944 bowling alley, and extensive facilities for groups and events. As a result, Arche Mielno is a place suited to holidays, family trips, senior stays, conferences, galas, concerts and corporate team-building events alike.History that has not been locked away in a display case
At Arche Mielno, history is not merely an add-on. It is part of the experience. You can see it in the scale of the hangar, the industrial details, the layout of the space and the stories told by the guides. It is a place that reminds us that architecture can preserve memory while still serving modern guests. ARCHE Fabryka Samolotów in Mielno is a story of transformation — from military infrastructure and a closed-off site to an open seaside hotel that combines leisure, culture, meetings and the authentic heritage of the place.History of the Nest base
On January 1, 2017, the rural municipality changed its status to urban-rural. As a result, Mielno became a town, and Unieście was incorporated into its boundaries. Mielno operated under the German name Großmöllen, while Unieście was known as Nest. Before World War I, a military base was constructed that served the German naval aviation. Remnants can still be seen around Lake Jamna. During World War I, the base had over a thousand modern (for that time) airplanes, seaplanes, and flying boats. After the war, due to the provisions of the Treaty of Versailles, the base served civil aviation. Before World War II, the government in Berlin decided to return to that solution. Around 30 facilities were created – from hangars, through warehouses, to barrack buildings. During World War II, Mielno, Unieście, and Łazy served as a testing ground for German aviation. The German chapter in the history ended when on March 5, 1945, units of the Red Army entered Unieście, abandoned by the Luftwaffe, occupying the air base. After two years, the Red Army handed over the area and the facilities located there to the units of the Polish People's Army, which used them until the end of the 1990s. Among the residents of Unieście, there are stories about underground tunnels, buried in sand, connecting the former military areas with the village center. Sometimes storms reveal hatch covers and fragments of walls – relics of the military past of these areas.
