The House "Under the Frogs" is one of the textbook examples of Polish Secession. The building located on the corner of the Wojska Polskiego Square, (the former White Market), in front of the Martin Luther Lutheran Church, has a fairytale architecture. It is known primarily for the portal, which is part of the sculptural composition of the two feasting frogs, one of which, leaning against the barrel, holds a glass, and smokes a pipe, while the other plays the mandolin.
