Hoser Tenement House in Warsaw

The Hoser Tenement House is a five-story building at Aleje Jerozolimskie 51 with floral decorations throughout its facade. Sunflower stained glass windows and metal flower railings frame the balconies along the exterior walls.

Construction took place between 1904 and 1905, replacing the original horticultural establishment of the Hoser family on this site. The new building served as offices and retail space for their growing seed trading business.

The building carries the Hoser surname from the brothers who established their horticultural business here and used it as their trading hub. Visitors can observe how floral decorations throughout the facade reflect the gardening heritage embedded in this place.

The building houses the Warsaw Branch of PTTK Tour Guides and the Biegas Museum inside its walls. Visitors can explore the interior and get information directly from the organizations located here.

Inside sits Europe's oldest still-working kaiserpanorama, a cylindrical device for viewing stereoscopic photographs from a bygone era. This apparatus has remained in its original spot since 1905 and continues to intrigue visitors.
