The Church of the Holy Cross (Episcopal), which housed St. Mark's until 1954, is a historic church at 875 Cotton Street in Shreveport, Louisiana, United States. The first services of the Episcopal church in Shreveport were celebrated by the Rt. Rev. Leonidas Polk, the Bishop of Louisiana in March 1839. That liturgy is considered the founding day of St. Mark's Church. Prior to this church building, the church was located on Fannin Street. St. Mark's moved into a new church building at Fairfield Avenue and Rutherford Street in 1954. That church became the cathedral of the Diocese of Western Louisiana on July 7, 1990.
