The palace in Jankowice was built in 1803 on the site of the former Twardowski manor. Its original form refers to the avant-garde neoclassical trends, fashionable at the turn of the 18th and 19th centuries in the Berlin milieu. The architecture of the palace – villa at the time of its construction was considered extremely modern.
In this form (with a winter garden added at the end of the 19th century), the building survived for over 100 years. In 1912, it was expanded by adding side wings and two terraces, designed by the outstanding Poznań architect Roger Sławski.
After World War II and the nationalization of the Jankowice estate, there was a production cooperative on the manor farm, and a training center was set up in the palace.
Later, the building was given to a student organization. From the 1990s, the building slowly deteriorated. In 2005, the palace and the park were taken over by the Municipality of Tarnowo Podgórne, which in 2016-2018 carried out a major renovation of the building from its own funds (cost EUR 5 million).
Today it is a place for meetings and interesting cultural events.
