Sights and history

Ostrów Tumski and the Archcathedral

Ostrów Tumski (Cathedral Island) lies between the Warta and the Cybina rivers. In the 10th century it was the site of a stronghold of the first Piast rulers. A bishopric has existed here since 968, and the Archcathedral of St Peter and St Paul is the oldest cathedral in Poland.

About the place

The first cathedral was built in the 980s. The present building is Gothic, from the 14th and 15th centuries. After the destruction of the Second World War it was partly rebuilt and its Gothic character was restored.

Poland's first rulers are buried in the cathedral, among them Bolesław the Brave, Mieszko II and Casimir the Restorer.

What to see

The Golden Chapel (Chapel of the Polish Kings), built in 1836–1837: an octagonal mausoleum in the Byzantine style, dedicated to Mieszko I and Bolesław the Brave. It stands exactly on the axis of the church.

The cathedral crypts: remains of earlier buildings, the tombs of the Piast dynasty and a 10th-century baptismal font.

The viewing tower, open seasonally (in 2026 from 1 June).

Good to know

The cathedral is a working church. It cannot be visited during Mass, services or concerts, and you are asked to dress modestly and keep quiet.

Across the Cybina, connected by a footbridge, stands the Gate of Poznań (Brama Poznania). It offers a combined ticket for visiting Ostrów Tumski.
