The "Haus Löwenstraße 1" (House at Lion Street 1) stands at the fork between Niemenstraße and Löwenstraße. It is built totally in Jugendstil (Art Nouveau) and is thus one of the city's most important private residence and commercial buildings. (The Salvation Army owns it since 1923).

Between 1905 and 1908, the building contractor Hermann Schupp used the plans of the Jewish architect Arthur Levi (banned by the Nazis in 1933) to construct the house.

The imposing house, with its five story front, curved gable, two balconies, sloping roof and tower-like windows on the right side, seems to rule over the small three-cornered square leading to the Kaiser-Joseph-Straße.

The supporting joints between the three entrance arches and the wide lower balcony form the mythological figures of two half nude bacchanals with musical instruments who flank the flute playing Pan in the middle.

The Löwenbrunnen (Lion Fountains) from 1908 are found before the corner slopes to the Löwenstraße .
