Szlenkier Palace, Renaissance Revival palace in Śródmieście, Poland.

Szlenkier Palace is a Renaissance Revival palace in Warsaw's city center featuring white marble stairs and Ionic columns. The building combines these classical elements with decorative details inspired by the Italian Palazzo Davia Bargellini in Bologna.

The palace was built between 1881 and 1883 for merchant Karol Jan Szlenkier. The Italian diplomatic mission acquired the building in 1922 as their headquarters.

Karol Jan Szlenkier had the palace built as a family residence and business seat: offices occupied the ground floor, the family lived on the first floor, and the upper rooms housed household and office staff. The interior encaustic paintings were made by Wojciech Gerson, and the staircase has column shafts of dark red marble with white bases and capitals.

The building is located at Jana Henryka Dąbrowskiego Square 6 in Warsaw and currently functions as the Embassy of the Italian Republic. Visitors should note that as an active diplomatic mission, access to the interior may be restricted or require prior arrangement.

The portal's atlantes, which supported a first-floor balcony, were modelled on the portal of the Palazzo Davia-Bargellini in Bologna. They were not rebuilt after the war damage of 1944, so the present entrance is simpler than Lanci's design. The steep roof with a baluster attic recalled French late Renaissance work.
