following years, additional aspects were rebuilt and renovated. The original, conical shape of the towers was restored only in 1991. The cathedral holds the largest pipe organ in Poland, built in 1913 by E.F. Walcker & Sons of Ludwigsburg, Baden-Württemberg, Germany, for the Centennial Hall — formerly the largest organ in the world. Architecture and furnishings The current cathedral is a three-nave Gothic oriented basilica surrounded by an ambulatory. The cathedral has three entrances: the main western portal and two later entrances from the north and south. Chapels Behind the choir are three chapels: Chapel of St. Elizabeth in the south was built 1682-1700 as the mausoleum of Bishop Frederick of Hesse-Darmstadt. The chapel was dedicated to St. Elizabeth of Hungary, whose cult had been popular in the city since the Middle Ages. It is a fine example of baroque architecture and forms the counterpoint of the Elector's Chapel. The design was probably the work of Giacome Schianzi, who is also credited with the paintings in the dome, which, along with wall paintings by Andreas Kowalski, show the death, burial, and heavenly glory of St. Elizabeth. The statue of St. Elizabeth was created by Ercole Ferrata, a student of Bernini's. Facing the altar on the other side of the chapel is the cardinal's tomb, the work of Domenico Guidi, another of Bernini's pupils. It depicts the kneeling cardinal surrounded by allegories of Truth and Eternity. Above the door to the church is a bust of the cardinal executed by the workshop of Bernini. The Gothic Marian Chapel directly behind the choir was built by the architect Peschel under the orders of Bishop Przecław of Pogorzela from 1354 to 1365. Apart from the tomb of its founder it is also contains the tomb of Bishop Johann IV Roth, the work of Peter Fischer the Elder of Nuremberg. A famous story from World War II concerned a famously beautiful marble statue of the Virgin and Child, created by Carl Johann Steinhäuser in 1854, that was kept in the chapel. When the Russians bombed the cathedral, the flames miraculously stopped in front of the fallen statue, preserving the three back chapels from destruction. Despite the fall, bombing, and general destruction, the statue remained unharmed. The northern Baroque Elector's Chapel, or the Chapel of Corpus Christi, was built from 1716 to 1724 as the mausoleum of bishop Count Palatine Francis Louis of Neuburg. Francis
