Cathedral Basilica of Saints Peter and Paul

Beginning in 1846, It took 18 years to build this world class monument to Cathoic faith. Today, the Cathedral stands as a living testament to William Penn’s dream of religious liberty. In England, Catholics had not been allowed to worship publicly, but they thrived in Pennsylvania. Yet, their story is not without struggle in testing the brotherly love and tolerance principles of the founder. Pope John Paul II celebrated mass here in 1979, as did Pope Francis in 2015.
