St. Mary's Basilica is a Gothic-style church located in the Main Market Square of Krakow, Poland. The church was originally built in the early 13th century but underwent several additions and renovations over the centuries. The basilica is renowned for its striking brick façade and twin towers, one of which is taller than the other.

The interior of the church is just as impressive as the exterior, featuring a stunning high altar and a number of intricate chapels adorned with frescoes and stained glass windows. The most famous feature of St. Mary's Basilica, however, is the wooden altarpiece, known as the Veit Stoss Altarpiece, which dates back to the late 15th century. This masterpiece of Gothic sculpture is over 40 feet tall and depicts scenes from the life of the Virgin Mary and the Passion of Christ.

St. Mary's Basilica also has a rich history, having served as the coronation site of many Polish kings and as a place of worship for the Polish people during times of war and occupation. Today, it remains one of the most popular tourist attractions in Krakow and continues to be an important religious center for the local community.
