The St. Paul Episcopal Cathedral (1852) was located on the southeast corner of Seventh and Plum Streets, in Cincinnati, Ohio. The church was across from the Saint Peter in Chains Cathedral and next to the Plum Street Temple. The original St. Paul's Episcopal Church was located at 111 East Fourth Street. The congregation was formed in 1828 by the Rev. Samuel Johnson, pastor of Christ Church. He had been unable to collect two years of back pay. He won over a sizable portion of the flock to the new church. In 1883 the church merged with St. John's Episcopal Church at Seventh and Plum Streets, which had been formed by the Rev. Nicholson in 1851. The church became the cathedral of the Episcopal Diocese of Southern Ohio. One guidebook writes of the church, "For decades after the completion of this stately church in 1852, elegant and fashionable Cincinnatians worshiped there." The Rev. Nicholas Hamner Cobbs served this church for several years before becoming Bishop of Alabama. Salmon P. Chase was superintendent of the Sunday school. The building was demolished in 1937. Many of its members had moved to the suburbs. Today Christ Church Cathedral on Fourth Street is the seat of the Episcopal Diocese of Southern Ohio, and the chapel in the diocesan headquarters next door (which also houses the Forward Movement) is named after St. Paul.

H. W. Derby Building is a registered historic building in Cincinnati, Ohio. The building was designed by architect Samuel Hannaford. It listed in the National Register on March 3, 1980. The firm of H. W. Derby & Co. acted as a jobbing outlet "for such large eastern houses as Harpers and Appleton", operated the largest and most elaborate bookstore in the West, and was well known in the Ohio Valley. H. W. Derby had an extensive publishing business of law books, medical books, and "miscellaneous" publications, "his law book line being unrivaled in the West" and his works of history, biography and travels, "received a new impetus with the passage of the act establishing the Ohio School Library in 1853." This law, "which Derby had zealously promoted, provided a tax for the support of libraries in school districts throughout the state, and the books for these collections were largely supplied by Derby from the publications of Harpers (who in 1839 had secured a monopoly to supply the New York School District libraries), Appleton, Derby & Jackson, and his own house."Architect John R. Hamilton's firm Hamilton & Rankin had designed the previous H. W. Derby Building, "Derby's Building" at the southwest corner of Third and Walnut (razed).H. W. Derby opened a New York gallery, the Institute of Fine Arts, at 625 Broadway, but "it is likely that this enterprise was a casualty of war" because a few years later he was exhibiting foreign paintings around the country "one of which, Dubufe's "Prodigal Son," burned in Smith & Nixon's hall in Cincinnati. In the late 1870s he returned to Columbus, Ohio and after a few years again moved on to Cincinnati, where he erected an impressive business block, the Derby Building, which later burned.."
