The Archaeological Reserve features a unique display of the Poznań settlement’s defensive embankments, which were an impressive feat of 10th-century engineering and technological design.
This historic builder of the Polish state faced huge challenges in his attempt to establish a strong power centre. To achieve his goal, he took advantage of the natural defensive features of the island on which he established a settlement in the 10th century. The settlement was surrounded by massive 10 meter-high embankments with a total length of ca. 2 km! Their remnants can still be seen in the Archaeological Reserve. At the turn of the 11th century, the Poznań settlement served as the country’s capital: it was one of the main seats of the first rulers of Poland.
The Archaeological Museum also offers a 3D documentary on the construction of the Cathedral Island settlement. You can tour the exhibition with an audioguide. Shown on display are remnants of Cathedral Island’s former defence system, including a 10th-century embankment erected by Mieszko I and a 16th-century defensive wall built by Bishop Jan Lubrański.
