Discovery of the Altar Fragments
During a routine inspection of the crypt beneath the Church of the Visitation of the Blessed Virgin Mary on Przyrynek Street, staff from the Mazovian Provincial Office for the Protection of Monuments identified stone decorations hidden since World II. Dr Piotr Jamski and Dr Marcin Zglinski of the Institute of Art of the Polish Academy of Sciences examined the pieces and determined they are fragments of a Renaissance altar, not a tombstone as first thought. The fragments survived fire, post-war explosions and damp before being cleaned and moved to a temporary lapidarium.
Historical Background of the Church
The church was erected between 1409 and 1411 with funding from Princess Anna of Mazovia and consecrated in 1411. Originally a single-nave structure, it was expanded into a three-nave basilica at the end of the 15th century. It underwent Baroque rebuilding after the 1656 Swedish Deluge, Neo-Gothic and Neo-Romanesque alterations in the 19th century, and a 20th-century restoration that removed many later additions. The building suffered severe damage in September 1939 and during the 1944 Warsaw Uprising; reconstruction was completed in 1956.
Attribution and Significance of the Altar
Researchers date the altar to roughly 1565–1580 and attribute it to Jan Michalowicz of Urzedów, a leading Polish Renaissance sculptor. The attribution rests on stylistic parallels with Michalowicz’s known work on Wawel tombstones. Stone altarpieces from this period are rare in Poland, making the find a unique addition to the nation’s Renaissance heritage.
Physical Description and Condition
The altar was carved from Pinczów limestone and originally rose 5.82 m. Surviving elements include carved column shafts, sections of the entablature, a frieze with Passion symbols, and a fragment of the central Crucifixion relief. Traces of gilding and coloured polychromy remain despite exposure to fire, explosions and moisture. The recovered pieces represent about 17.5 % of the altar’s front surface.
Preservation Efforts and Future Plans
After cleaning, the fragments were transferred to a temporary lapidarium alongside other church furnishings. Researchers are preparing conservation treatments and evaluating the feasibility of a full reconstruction. The discovery has prompted renewed interest in further archaeological work within the church’s foundations.

Their survival illustrates the resilience of cultural heritage hidden beneath urban layers and offers the possibility of restoring a missing visual element to the historic church.
