The Cathedral of Saint Jude the Apostle is a Roman Catholic cathedral located in St. Petersburg, Florida, United States. It is the seat of the Diocese of St. Petersburg. St. Jude Parish was founded in 1950.[3] The first church building, now Our Lady's Chapel, was completed the following year. As the parish grew larger a combination school and church building was completed in 1954. The present church building, a Modern interpretation of the Byzantine style in the form of a Latin cross, was built in 1963.[4] When Pope Paul VI established the Diocese of Petersburg on March 2, 1968, it became the cathedral of the new diocese.[5] The cathedral underwent a $9 million renovation from 2012 to 2013.[6]
