Churches and monasteries are the largest category in the tripto catalogue: 553 cathedrals, shrines, abbeys, Orthodox churches and mosques. To start, pick a few places that differ the most from each other.
Jasna Góra in Częstochowa is the Pauline shrine with the Chapel of the Miraculous Image and a 106-metre tower – entry to the chapel, basilica and ramparts is free. Gniezno Cathedral on Lech Hill holds the tomb of St Adalbert and the Romanesque Gniezno Doors from the 12th century. The Church of Peace in Świdnica (UNESCO) is the largest wooden Baroque Protestant church in Europe, built in ten months in 1657, with galleries for 7,500 people. In Kraków, Wawel Cathedral combines the Sigismund Chapel, the Sigismund Bell and the royal tombs. The Kruszyniany Mosque feels completely different – it is the oldest surviving Tatar mosque in Poland, first mentioned in 1717.
Most places in this category are in Lesser Poland (more than 80) and the Silesian region (more than 70), followed by Greater Poland (close to 50) and Podlachia and Opole (close to 40 each). Kraków alone has almost 20.
In practice: you can enter most churches without a ticket, while towers, crypts, treasuries and museums often charge – the crypts of Warsaw's archcathedral cost 5 zł. Sightseeing is usually not possible during mass. Churches work well on a rainy day or as a short stop on a road trip, as an average visit takes 40–75 minutes. With children, go for the viewing towers and the astronomical clock in St Mary's Basilica in Gdańsk, whose figures move at 11:57.
