Among the most noteworthy churches of Syracuse are the Roman Catholic cathedral of the Immaculate Conception - Syracuse became the see of a Roman Catholic bishop in 1887 - and St Paul's Protestant Episcopal, the first Presbyterian, first Methodist Episcopal, Dutch Reformed and May Memorial (Unitarian) churches, the last erected in memory of Samuel Joseph May (1797-1871), a famous anti-slavery leader, pastor of the church in 1845-1868, and author of Some Recollections of Our Anti-Slavery Conflict (1873).
