3 Piotrkowska Street in Łódź, 19th century tenement house on Piotrkowska Street, Łódź, Poland.

Kamienica Antoniego Engela at 3 Piotrkowska Street is a one-story brick building from 1853, designed by Karol Mertsching as the Hotel de Pologne. Its ground floor has seven windows (four facing the street), two front doors and two double-wing gates; the upper floor has ten windows, seven on Piotrkowska. A gallery runs along the courtyard side, and the attic has two windows.

Before 1853 the plot held a single-storey wooden weavers' house with five rooms and a shop, owned by Antoni Engel. In 1853 Engel replaced it with a one-storey brick inn, the Hotel de Pologne, designed by architect Karol Mertsching. In 1872 Teodor Engel took over and turned the ground-floor tavern into a restaurant. After World War II the building became flats and lost its stucco.

The name Hotel de Pologne, given by Antoni Engel to his 1853 inn, is French rather than Polish, a mark of the prestige such a name carried in the city. Meals were served in a ground-floor tavern with a liquor licence; in 1872 Teodor Engel replaced it with a restaurant. The narrow rear courtyard is now the Pasaż Róży, a passage designed by Joanna Rajkowska.

The passage runs between Piotrkowska Street and Zachodnia Street, so you can walk through the courtyard rather than backtrack. The mirror mosaic lines the annex walls of this narrow passage, which is brightest on sunny days and also lit at night by artificial light and the moon. Look for the passage entrance in the gateway of the tenement house.

The narrow courtyard behind the building became Pasaż Róży, a passage linking Piotrkowska Street with Zachodnia Street, designed by artist Joanna Rajkowska. Its annex walls are clad in mirror mosaic made of thousands of small pieces of light-reflecting glass, not the whole courtyard. The passage is bright on sunny days and also lit at night by artificial light and the moon.
