The Cathedral of the Immaculate Conception in Philadelphia is a Ukrainian Catholic cathedral located in the Poplar neighborhood. It was established in 1886 and was designed by Julian K. Jastremsky in the Byzantine Revival style, modeled after St. Sophia (or Hagia Sophia now) in Istanbul (Constantinople). The dome’s interior features a mosaic of Jesus Christ surrounded by saints.
The cathedral contains the remains of Philadelphia's Ukrainian Catholic bishops, including Bishop Soter Ortynsky, OSBM, native of Zakarpats’ka Ukraine, first bishop of all Greek Catholics in America; Archbishop Constantine Bohachevsky, our first Metropolitan-Archbishop of USA; and Archbishop Ambrose Senyshyn, OSBM, who built the present Cathedral building. The basement level also houses the Museum of Faith staffed by the Missionary Sisters of the Mother of God.
