The Karol Poznański Palace in Łódź, built in 1904 for the son of Izrael Poznański, is an impressive example of Neo-Renaissance architecture inspired by Florentine palaces. Designed by Adolf Zeligson, the palace served a representational function and was intended exclusively for residential purposes. Its interiors are adorned with lavish decorations, such as intricately crafted wood paneling made from various types of timber, stucco ceilings, marble fireplaces, and elegant furniture. Particularly notable is the internal staircase with its fan-shaped steps, lined with marble and embellished with a beautiful stained-glass window. The building consists of a front section and two side wings, with a bay crowned by a dome at the corner. From the street, the palace is separated by a fence decorated with mascaron ornaments and the letter "P" on heraldic plaques. An interesting fact is that this was the first building in Łódź to feature central heating already at the design stage. Today, the palace houses the Academy of Music in Łódź, underscoring its importance in the city's cultural sphere. It is worth emphasizing that the palace's architecture not only reflects the wealth and prestige of the Poznański family but also aligns with the development of Łódź as a significant industrial and cultural center in the early 20th century.
