Gniezno Cathedral

Gniezno Cathedral (Gniezno is pronounced roughly "GNYEZ-no") – formally the Primatial Basilica of the Assumption and St. Adalbert – is where the story of Poland as a Christian kingdom begins. Its first archbishopric was founded here in the year 1000, five rulers were crowned under its roof, and the relics of St. Adalbert, Poland's patron saint, rest in a silver coffin above the high altar. Add the 12th-century bronze Gniezno Doors, an underground route and a tower terrace, and you have the essential stop on Poland's Piast Trail.

Where it is and how to get there

Gniezno is a small city in Greater Poland (Wielkopolska), about 50 km (30 miles) east of Poznań. Trains from Poznań take under an hour, and the drive is about 45 minutes; Poznań has the nearest international airport, while Warsaw is roughly 3–3.5 hours away by train or car. From Gniezno railway station it is about a 1 km walk through the Market Square and up Tumska Street to Lech Hill (Wzgórze Lecha), where the cathedral stands.

A short history: the cradle of Poland

An oratory stood on Lech Hill by the end of the 9th century, and Duke Mieszko I – the ruler who brought Christianity to Poland in 966 – built a cross-shaped church here at the end of the 10th. In March 1000, Holy Roman Emperor Otto III came to pray at the grave of the martyred missionary St. Adalbert. At this Congress of Gniezno, Poland got its own archdiocese, independent of German bishoprics, with Adalbert's half-brother Radzim Gaudenty as its first archbishop.

Gniezno saw the coronations of Bolesław the Brave in 1025 – Poland's first king – and of four more rulers up to 1300. The church was sacked by the Teutonic Knights in 1331, after which the present Gothic cathedral was built; its chancel and nave were completed by the end of the 14th century. Fires in 1613 and 1760 brought down towers and roofs, and in 1945 the cathedral burned after Red Army shelling; postwar restoration returned it to its Gothic form. Since 1419, the archbishops of Gniezno have held the title of Primate of Poland. The cathedral became a minor basilica in 1931 and a national Monument of History in 1994, and Pope John Paul II prayed here on June 3, 1979.

Things to see inside

• St. Adalbert's silver coffin – made in 1662 by Gdańsk goldsmith Peter van der Rennen, replacing an earlier one stolen by Swedish troops in 1655.
• The Gniezno Doors – a pair of bronze doors from around 1175, among the finest Romanesque works in Europe. Their reliefs tell the life and martyrdom of St. Adalbert, who was killed in 997 while trying to convert the Old Prussians. They are shown on a guided visit included in the ticket.
• The underground route – remains of the earlier pre-Romanesque and Romanesque churches and graves, visited with a guide.
• The tower terrace – views over Gniezno and its lakes, open May to October.
• The Archdiocesan Museum next door – the cathedral treasury and religious art.

Is it worth visiting? Tips

Yes – for anyone interested in Polish or medieval European history, Gniezno is as important as Kraków's Wawel. Allow 1.5–2 hours for the cathedral, Doors and underground, and half a day with the terrace and museum. Come on a weekday morning; weekday Masses at noon and 6 pm limit sightseeing. Dress modestly and keep quiet – this is a working church. The terrace and underground are reached only by stairs. The all-inclusive pass includes a free audio guide; ask at the ticket office which languages the guides and audio guide currently offer.

Nearby

On Lech Hill you'll also find St. George's Church, and by Lake Jelonek the Museum of the Origins of the Polish State. About 20 km west lie Ostrów Lednicki, an island with ruins of an early Piast palace, and the Lednica Fields. Gniezno is a key stop on the Piast Trail, which continues to the Iron Age settlement of Biskupin and to Strzelno.
