The Palm House was designed by S. Cybichowski in 1929 and underwent extensive renovations in the period of 1982 to 1992. With its impressive collection of 17 thousand plants from 700 different species and subspecies originating from a variety of climates such as the Mediterranean, subtropical, tropical, savannah and desert, the Palm House has become a renowned institution in Europe.
Furthermore, visitors can enjoy the sounds of exotic birds living in the Palm House, listen to the tranquil sound of flowing water, and admire a variety of exotic fish swimming in tanks and ponds. The building is comprised of 9 large rooms, where exhibitions are organized based on the different climate and plant zones, including tropical, subtropical, moderate, American succulent, water plants, tropical forest floor, savanna, xerophytes of the Old and New World, and fish tanks.
In addition to the Palm House, the Wilson Park also features a public air raid shelter that was built in 1944 for Germans residing in the luxurious apartment buildings on Matejki Street. This historical facility was only uncovered in 1998 during the renovation of Wilson Park and the Palm House. Visitors are only able to tour the air raid shelter with a guide.
