St. Mary's Basilica, also known as the Mariacki church, lies at the northeastern end of the old town square. The church has been built in Gothic style with bricks between the 13th and 15th centuries. It is characteristic for its Romanesque towers which are of different heights and have different spires. The interior of the Mariachi church is impressively decorated with beautiful elements in every possible corner. The high wooden altar of Veit Stoss is famous.
