The Castle served as a residence for Polish kings since the 13th century. Within its walls crucial decisions concerning the state were made by Poland’s rulers, who wanted to ensure the country’s stability and growth. It was here in the 13th century, for example, that Przemysł II sought to reunite Poland into a single country after nearly 160 years of fragmentation. It was also in the Caste, in 1493, that John I Albert received homage from the Grand Master of the Teutonic Knights Johann von Tiffen, who acknowledged his state’s submission to the Polish King. The Castle was not only the residence of the monarch but also Poznań’s last line of defence. Situated atop a hill, it towered over the city as a symbol of royal power.
