Łowicz Cathedral

Łowicz Cathedral (say "WO-veech"), formally the Cathedral Basilica of the Assumption and St. Nicholas, stands on the Old Market Square of a small town in central Poland and is nicknamed the "Wawel of Mazovia". It is the burial place of twelve Archbishops of Gniezno and Primates of Poland, the church's highest-ranking prelates, who for centuries owned and often lived in Łowicz. A Baroque interior lined with burial chapels, Renaissance tombs, the primates' crypts and a viewing terrace on the tower make it one of the most rewarding sights between Warsaw and Łódź.

Why the primates matter

In the old Polish-Lithuanian Commonwealth, kings were elected. Between the death of one king and the election of the next, the Primate of Poland acted as interrex — temporary head of state. Because the primates owned Łowicz from 1136, the town's collegiate church served from 1572 as the most important church of the Commonwealth during each interregnum.

History in brief

A wooden church was founded here around 1100, and a brick Gothic church followed around 1355. On April 25, 1433, it became a collegiate church. Primate Henryk Firlej began rebuilding it in Baroque style in 1625; the architects Tomasz and Andrzej Poncino carried on under Primate Maciej Łubieński, and the church was reconsecrated on October 14, 1668. It was badly damaged during the Battle of the Bzura in September 1939 — one of the largest battles of the German invasion of Poland — and restored after the war. In 1992 it became the cathedral of the new Diocese of Łowicz, and in 1999 Pope John Paul II made it a minor basilica.

Since November 13, 2012, the cathedral has been a Monument of History, the highest national heritage designation in Poland.

What to see inside

• Burial chapels — including the Uchański Chapel (1575–1580) by the Renaissance sculptor Jan Michałowicz of Urzędów and the Tarnowski Chapel with a Renaissance tomb carved by Willem van den Blocke.
• The primates' crypts — burials including Henryk Firlej in a tin sarcophagus and Andrzej and Wacław Leszczyński; the previously sealed crypts were opened around 2024.
• Our Lady of Łowicz — a venerated image honored since 1719 and crowned in 2002.
• Relics of St. Victoria, patron of the town, kept in Łowicz since 1625.
• A 42-stop organ and a Baroque portal with Primate Łubieński's 1652 foundation plaque.
• The tower viewing terrace overlooking the town.

Look out, too, for the Lipski Chapel (1641–1647), with an altar by Jakub Fontana, and the marble altar in the Uchański Chapel funded by Primate Łubieński after the Polish victory at Berestechko in 1651. Allow about half an hour for the church alone and two hours with the museum, crypts and terrace.

Tickets, tours and opening hours

You can see the church on your own outside service times (weekday Masses at 7:00, 7:30, 8:00, 9:00 a.m. and 6:00 p.m.). The Diocesan Museum, crypts and viewing terrace can only be visited with a guide, booked in advance. As of October 2026:

• Monday–Friday 10:00 a.m.–3:30 p.m., Saturday 10:00 a.m.–2:00 p.m.; no Sunday tours are listed

Book and buy tickets at the museum office in the diocesan bookshop at Stary Rynek 20 (tel. +48 46 837 66 45). The information is in Polish, so it's worth asking whether an English-speaking guide is available when you book; crypt groups are limited to 15 people. Because everything is indoors, it's a good winter outing — just remember to book ahead.

How to get to Łowicz

Łowicz lies in the Łódź region between Warsaw and Łódź, close to the A2 motorway. Trains stop at Łowicz Główny station, from where the Old Market Square is a walk away — an easy day trip from Warsaw without a car. Warsaw Chopin Airport is the nearest major international airport.

Is it worth visiting?

Yes, especially if you are interested in Polish history beyond Kraków and Warsaw. Time your trip for Corpus Christi (late May or June) and you'll see the famous procession in colorful Łowicz folk costumes, listed as national intangible heritage in 2014; the town's Regional Museum shows the costumes year-round.
