Superlatives fail to describe the interior of St. Mary’s Basilica. Everything below the blue-star vaulted ceilings is awe inspiring. Each inch of the columns and arches is intricately painted with ornate designs and murals. The stained-glass windows glisten with medieval glory. Impressive religious sculptures abound in niches, side aisles and chapels. Elaborate tombs are everywhere. The organ pipes in the nave gallery are accented with angels playing musical instruments. And the pièce de résistance of Kościół Mariacki is the late-15th century wooden Gothic altarpiece by sculptor Veit Stoss, the largest and some claim the best one in the world.
