Arche Group to open hotel in former Białystok garrison

The Arche Group is completing the revitalization of a former imperial garrison in Białystok, Poland. The project, located at Depowa 9a, will transform historical buildings—including former stables, a prison, and a kitchen—into the Hotel Arche Garnizon.

The complex is scheduled to open in the third quarter of this year, with a planned opening in early September. The development will feature approximately 200 rooms (420 beds), a restaurant, a SPA, conference rooms, and an event space. The project aims to preserve the historical character of the site while integrating new hotel structures to complement the existing heritage buildings.
