The Černá růže Passage forms an architectural connection between the historic building at Na Příkopě and the functionalist Bondy House at Panská. While the older building dates from the 1840s and originally featured a Romantic-style façade, the Bondy House reflects the modernist approach to commercial architecture that emerged in Prague during the interwar period.
Designed by architect Oldřich Tyl and completed in 1932, the Bondy House established the architectural character of the modern passage. The house's façade in Panská Street is slightly set back between the first and third floors and is framed by a band incorporating lighting. The relatively large windows define the rhythm of the façade. The top floor is set back, creating a terrace. As is typical of this part of Prague, an additional storey was added at a later date, after 1990.
The passage was conceived as an integral part of the new commercial development, sharing its modernist design language while being physically connected to the older building on Na Příkopě.
One of the passage’s most remarkable architectural features is its vaulted roof made of glass concrete, which was reportedly the largest of its kind in Europe at the time. The translucent structure allows natural light to penetrate the interior, creating a bright and distinctive environment. The same principle is reflected in the glass-concrete galleries on the upper floors, which admit daylight while preserving the passage’s open spatial character.
The reconstruction carried out in the 1990s sought to preserve the passage’s original architectural details. These include the floor tiles and the original door handles used to open the shop doors. The passage is divided into two sections. The shorter section, facing Panská Street, has any escalators and therefore appears to have retained a more original state. At the same time, the longer section, facing Na Příkopě Street, has escalators instead, which had not been part of the original design. The two sections connect directly on the ground floor, while on the two floors above they are linked by a narrow passageway.
